American Partisan: Home Brew – NVIS Antenna

Johny Mac at American Partisan has an article up at American Partisan on making your own NVIS antenna. A near-vertical incidence skywave (NVIS) antenna is used in the high frequency (HF) spectrum from around 1.8MHz to  10MHz in order to cover an approximate radius/range of 300 miles. HF is usually used for long distance communication around the world, and most antennas are built to maximize range, but those antennas can often cause the radio signal to skip or make a gap in the range from about fifty to three hundred miles.  The NVIS antenna redirects the radio signal in such a way that it covers that gap at the sacrifice of the longer distance contacts. This makes the NVIS antenna ideal for communications during a regional disaster.

If you do not know what a NVIS antenna is and why it is a great addition to your antenna farm, go and read these four articles. The first being from NC Scout titled, Near Vertical Incidence Skywave – Simplified, then NVIS I, NVIS II, and NVIS III authored by Key Pounder and published on NC Scout’s site, Brushbeater.

At a 100,000-foot level though, a NVIS antenna is a dipole antenna that has a steeper transmit angle than a traditional horizontal flat-top dipole antenna and is located closer to the ground at between 8 to 15-feet Vs. a traditional 1/4λ height; let’s say 30 to 60-feet over tera firma. This allows you to transmit to other stations closer to your AO that you may skip over using a flat-top horizontal dipole antenna. Think of the skip bounced off the ‘F’ layer of the ionosphere being 25 to 50-miles Vs. 200 to 300-miles. The German Army developed this procedure during WW II to communicate with troops via the airwaves closer to the transmitting station.

Traditional dipole antenna radiation Vs. NVIS radiation

I started out building my NVIS antenna using the directions posted on the DX Engineeringsite as my blue-prints for the project. Although you can buy a kit from DX Engineering, I had plenty of hardware around the redoubt so I decided to save a few bucks. Below is my Mise en place for this build. Hams are the true scroungers of this earth…

AmPart: Directional Antennas for the Small Unit, Part I and II

NC Scout at American Partisan has started a series of articles on antenna theory called Directional Antennas for the Small Unit. If you’re just getting started in radio communication, or you’ve been using it for a while but haven’t spent much time getting to know your antennas, this is a good start.

Directional Antennas For The Small Unit, Part 1

One of the biggest misconceptions behind communications security revolves around misunderstanding not just the role of the equipment but also how it functions. A big part of that is the basics of antenna theory. For most radio seems to be a plug and play kinda deal- it either works, or it doesn’t. Antennas are a type of voodoo magic and the solution to security is electronic encryption. Except it isn’t, and doesn’t do anything except mask what you’re saying, but not the fact you’re saying it. Guerrillas must rely on not being detected- and no matter how high tech you think you are, it’ll not solve a tradecraft issue.

The reality is that we’ll be working with equipment that is common and off the shelf- no matter how much we want those microwave NSA-encrypted troposcatter radios made of unobtanium, a big part of local networking is done via plain old VHF and UHF amateur and commercial gear that’s common. Guerrilla communications have to be harder to detect. And at the strategic level when building an underground network, you have to understand how to plan. Even with the cheap equipment most of you likely have, incorporating a level of planning into your local communications will yield a much higher level of security and success. Knowing and understanding directional antennas becomes a key part of that planning, and as we cover in the Advanced RTO Course, there’s several options that each get the job done.

Directional Antennas such as this Yagi seen here offer security by ‘beaming’ our transmission in the direction its pointed.

Directional antennas accomplish two goals for us. First, generally speaking, if you’re not in the direction of the transmission you’re not going to hear the traffic. Because of this it offers a big advantage in the security department. If two directional antennas are transmitting toward one another, they’ll be able to communicate with the only people hearing the full conversation being in the middle of the two people. The second advantage is that instead of all our energy going in all directional at once, as with an omnidirectional antenna, a directional antenna sends the same amount of radiated energy in one direction- greatly increasing our range and signal strength in that direction, so we won’t need nearly as much power to accomplish to reliably communicate over a distance you might not have thought otherwise possible…

Brushbeater RTO (Radio Operator) Course, Hamilton, MT – June 15-16, 2019

NC Scout of the Brushbeater blog will be holding his RTO Basic course again in Hamilton, MT (south of Missoula), on June 15 & 16, 2019. This is the only date on the calendar in 2019 that is in western USA.

Contact brushbeater@tutanota.com for class inquiries and to register.

The Radio Telephone Operator (RTO) Course is designed to take the individual of any and every experience level and teach them the basics of effective small unit communications in a field environment. Students will learn what it takes to set up a plan and implement communications in an improvised setting be it anything from a retreat to a security patrol to regional communications networking groups. A heavy emphasis of the course is on improvisation and antenna building- each student will construct antennas from improvised materials which they keep. This is NOT a “ham radio” class. No equipment or previous experience is required; only a notebook and a good pair of shoes. It is the only course of its kind offered anywhere, in a friendly, laid back and respectful environment.

This class will teach students the basics of communications at the Team or Squad Level in the field. Topics of instruction include:

  • Identifying Equipment Requirements
  • Writing a Signals Operating Index
  • PACE Planning for Communications
  • Basic equipment capabilities
  • Traffic handling
  • Improvised antenna types, uses and construction
  • Setting up and running an NVIS HF station
  • Message Formats
  • Setting up and communicating from a Hide site

Two day course will culminate in an field training event running a TOC station and Hide site in the field. Students will each build an antenna and demonstrate competency in team communications basics during the field exercise. Amateur Radio license qualification is helpful, but not required. This is NOT a ‘ham radio’ class but each student will come away with a basic understanding of a team’s communications needs in a tactical environment and how to best meet them under less-than-ideal circumstances. No equipment is required for this course; however, if students want to get field practice with their own gear, it is highly encouraged but done so at their own risk. Instruction is completely off-grid.

RTO Course: $300 per Student in advance

Dialtone: Are You Wearing a “Wire”?

Dialtone has a quick tip on how to stealthily gain some signals intelligence about your local RF neighborhood – Are you wearing a “wire”?

Quick and easy. Simple and stealthy. Just a Binding post to BNC connector. Add ear buds and drop the radio in a bag. Run close call and survey the RF landscape around you with no one even knowing. Don’t over think it. Just take a walk around and see what you get.

Brushbeater: Tasks for the Designated Commo Guy

If you’e the person who has been put in charge of communications for your group, NC Scout at Brushbeater blog has an article up outlining the basic tasks that you should be working on – Tasks for the ‘Designated Commo’ Guy.

…that’s where the challenge of the designated guy begins- competently training your people to that baseline.

First things first, you can never, ever expect to get anywhere if you fly so far over people’s heads they ignore you. Members of your group have to see the relevance in what they are doing or else its a doomed effort from the get-go. With communications, the tendency is for new people to get quickly overwhelmed and all of them are explicitly not looking for a hobby, they just want their equipment to work. If they didn’t have interest in communications before, chances are very high there’s an end goal in mind and its not experimentation. They want validation that whatever this was they spent hard-earned money on based on your recommendations actually does what its supposed to do. What you told them it would do. And if they don’t see the results, you’ve got an albatross around your neck. Everything begins with the basics. As we used to be told over and over again, there is no such thing as super-duper secret techniques, just mastery of the basics. And I’ve found that to be true of nearly every task in life- what might seem rudimentary to one guy might be a tough task to another; the goal is to build everyone up.

#1. Create a Local Network

The first big hurdle to cross is to establish communications among your people. Not in the tactical sense, but in the practical sense. Realistically, your neighbors and people who live within about a 30 minute drive are what you have access to as far as people go- should the balloon go up tomorrow, they’re the ones who matter…

Edit: NC Scout posted an update article based on questions that were sent in about the article above, Practical, Tactical: Training Questions from a Reader.

I got these questions from a reader based on the last couple of posts and its questions many have but don’t quite understand. There’s a lot of different reasons people begin to focus on communications, but when you boil it down, its one of two real necessities: either networking your group over an area, or, supporting tactical needs. The two goals are different, and while there’s some overlap, its a different mission set with different techniques.
I’ve began reassessing communications needs because like you said in an article recently, I as a ham have been ignoring the benefits of using non-ham comms somewhat.
This is a really common attitude. A lot of folks forget the advantages of license free options once they get a ham license. The thing about amateur radio is the great pool of resources and nearly unlimited options you’ve got on the table. But not everyone in your group is going to get up to speed or even look into a hobby- it’s easier to defer to you, the subject matter expert, and do whatever you help them set up or suggest. Which normally means going license free.
I feel like there is a line between too little radio comms and too much though. I’ve always thought of it as a team leader and up sort of equipment, I.E. not every rifleman needs a radio. Even then, you still probably only need one radio that’s capable of communication outside the general area of the squad, in order to send reports etc. But on the flip side, in a MAG type setting, people need to be able to communicate with each other as well. So if you were to use FRS radios for your local non-tactical nets, wouldn’t that exclude them from use in a tactical situation? And then also GMRS as well, since it’s basically the same chunk of spectrum as FRS? And I don’t like the idea of relying on MURS with only 5 channels for tactical comms, although it would be simple. So other than CB, which is also channel based, I think I’m out of non-ham options, please correct me if I’m wrong though.
And this is getting into the heart of the question. There’s definitely a line between too much and two little, and it all revolves around the mission…

Brushbeater: Commo Tips for New Groups

NC Scout has an article up at his Brushbeater blog on communications tips for new preparedness groups, mutual assistance groups, or other groups needing radio communications – Commo Tips for New Groups.

I had the incredible experience of being a guest on authors Glenn Tate and Shelby Gallagher’s Prepping 2.0 podcast and radio show, and along the interview we covered common issues that I see a lot of preppers just getting into communications have. Since I’ve been running classes for over three years now getting people up to speed, there’s a several issues I see repeating over and over. But fortunately in every case, the answers are more simple than you think.

Understand Your Real Needs

I always point folks to their primary needs- creating local infrastructure. We can’t really control much outside of our primary Area of Operation (AO) or Area of Influence (AI), but what we an do is work to build up local infrastructure within those areas. And if that’s all you can do, but you’re actively doing it, then you’re lightyears past what others are doing. This means VHF and UHF capabilities, which are both very common and pretty inexpensive for basic equipment.

What should I buy?

This is the first question most people ask. Its the same with guns, trucks, tires, and anything else you can spend money on. The answer I come up with in class is that its not the equipment, its the capability; that means frequency ranges. That $25 Baofeng UV-5R operates on VHF and UHF frequencies, both licensed amateur (ham) and license free (MURS, FRS, etc)…

OH8STN: Grid Down EMCOMM Winter Edition

Julian at OH8STN.org is full of useful amateur radio information. In the piece excerpted below, he talks about winter emergency communications and the difference between preparing for emergency communications when there is a large logistics tail on the move to support you and emergency communications in a long term or grid down scenario. Here’s a bit from Grid Down EMCOMM Winter Edition:

EMCOMM VS Communications Preparedness

There’s a huge disconnect between the yellow vest wearing emergency communications Community within amateur radio, and those seeking to learn and or develop skills for communications preparedness. They both have completely different methodologies, but they are overlapping.

  • With EMCOMM (North American Edition), we almost always have an expectation of a large Logistics deployment machine, deploying resources after the fact. Hopefully this will change after the horrific lessons of Puerto Rico.
  • With Communications Preparedness, our focus is grid down Communications in the thick of the disaster. There’s no Logistics, no one’s coming to help right away, so we are left on our own, getting information into and out of an active disaster zone.

Right now neither the EMCOMM community or the Communications Preparedness crowd are speaking the same language. They simply don’t understand one another. I suspect anyone reading this blog, or watching my videos has a firm grasp of both sides of this “Niche within a niche” as my friend John calls it. This disconnect between the two communities is critical for understanding and ultimately deployment in the field…

AmPart: Wargaming Dangers to Your Area

NC Scout is full of useful information, and luckily he is willing to share that information with us all. In his post Situational Awareness and Wargaming Your AO, NC Scout gives us a short explanation about how to about thinking over how critical infrastructure in your area could be attacked. He’s particular interested in communication infrastructure, but the same targeting process can be used toward anything.

The most important questions you should be asking right now are not the hypothetical or abstract simply naming ‘SHTF!’, rather, it needs to be rationally rooted in the MOST LIKELY and MOST DEADLY courses of action (MLCOA / MDCOA). What causes this “SHTF?” Who will be taking advantage of it? One of the overtones of my recent classes has been discussing the growing local antifa movement and (somewhat) wargaming/red celling capabilities, with emergency services communications systems coming into question. Think on that one for a second. It’s a dangerous proposition that many overlook- there’s a real threat to the robustness of emergency service equipment and as we become more and more complex, they become more and more vulnerable. From my perspective, this makes understanding and maintaining my own off-grid communications and action networks that much more important. And it should you too…

This is not some overseas and out of mind terror group. This is Antifa in the US. And they’ve built a cadre of combat vets from their time fighting in Rojava. What have you been doing?

.Building independent, self-sustaining communities is paramount, as well as being the strongest survivalist plan, but its important to recognize that threats are more than just simplistic catch phrases. You still live in the real world, not that lustful libertariatopia, and are subject to the ramifications of threats external to you. I take people at their word- and the Left’s core, the ‘instant gratification‘ groomed social justice warriors, a manifestation of all of the fingers that threaten Western Sovereignty- are the future of their movement. They see no benefit to the current order and through willful ignorance find solace amid revolutionary ideals whose only logical end is violence. I believe them. And instead of useless projecting, you should be asking serious questions about what they’re capable of pulling off. I bet some folks in Nigeria today wished they had done a bit more in retrospect. I’d be willing to bet some of you will too- Antifa thugs, Islamic thugs, same types of people. They both want you, Christian Male, exterminated.

What to do now is get serious about a training schedule while spending some time understanding more about your individual area. There’s a lot of opportunities out there, and the more arrows you put in the quiver the more resilient you’ll be later on down the road.

American Partisan: The Jungle Antenna Revisted

NC Scout at American Partisan has written another article discussing the jungle antenna – The Jungle Antenna Revisited: Task and Purpose for the Partisan and Prepper. NC Scout has written about this antenna and its usefulness previously.

Going back to the early days of the Brushbeater blog, the Jungle Antenna post has been and continues to be one of the more popular posts I’ve done. And for good reason- I wrote it to be used. It’s the antenna every student in the RTO course builds and one of the designs they get hands on with, and it’s the one that they know works from the demonstrations we do with them. But often, as with everything, a context for the task and purpose has to be clarified.

Many preppers who contact me fall into a similar trap. I have a goal and recognize a need. What can I buy that does for me what I want it to do? How do I do this in the most cost-effective way? And finally (but what should be first) how do I obtain the skill to best use the gear I’ve purchased? It’s a problematic point of view for a lot of reasons but one I get frequenct questions about nonetheless. And that’s ok. I’ll normally answer it the same way- Use your stuff. Learn to use it even better, and never stop!

One of my objectives bak then, as it remains in my classes and writing today, was emphasizing the skill of building your own equipment…

Off Grid Ham: Introduction to AC Inverters

From Chris at Off Grid Ham, An Introduction to AC Inverters. Even if you’re already happily running all of your ham radio equipment off grid, at some point you might wish you could run something that wants 120V AC. If you’re not a ham radio operator, and you’re looking into running some household stuff from a battery/solar system, then you also are probably interested in learning something about AC inverters.

AC inverters are like other technology in that during the early  years they were very expensive and didn’t work particularly well. Over time they were tweaked and improved and today inverters are better and less expensive than their ancestors. I suggest including an inverter in your off grid plans even if you don’t think you need one because the day may come when it will be an essential asset. Furthermore, if you have any intentions of owning a larger solar energy system to power common household devices, then a familiarity with AC inverters is a must…There are three basic types of AC inverters on the market: Square wave, modified sine wave, and pure sine wave. Which one will work for you depends on what you plan on powering and of course your budget…
