Now that I’ve shown you a number of NON prepper-friendly antennas, maybe it’s time to show you some that are more in tune (sorry…) with your goals as a survivalist.
To recap, the big monster antennas, associated towers and rotors are simply not required. Indeed, they are — in some respects — counter productive to our efforts.
Because in pre-SHTF conditions, you’ll wish to be prepping for communications capabilities that do not attract attention. It’s certainly not that you’re doing anything improper, as indeed you are abiding by all the rules of your license, and are in fact providing a public service capability for yourself, your family, your extended group, and other like-minded groups around the country.
Herewith, the ultimate stealth antenna — the venerable dipole.
Please. Let me be the FIRST to state that having your antenna inside the house is the worst possible option. The only purpose of the picture is to give you easy visual access to what is truly a simple antenna. Try that at 70 feet up.
The antenna itself is actually just the two pieces of wire. Di-pole. Get it? One piece is the exact same length as the other, separated by an insulator. Insulator? Yes, we need a way to electrically separate the two sides of the dipole. I’ve made insulators out of wood, plastic garbage pails and even pieces cut from milk jugs.
There’s a specific (simple) formula that tells you how long to make the two pieces. That formula takes into account the frequency band that you’re interested in operating your digital prepper network node. Forty meters? Fine. That would be 33 feet on a side; now you know one reason why this isn’t going to be in your bedroom.
The vertical piece of wire is actually a length of coax cable which goes from the center of your dipole, down to the radio, so with that in mind, you can gauge the approximate length.
There are as many variations of the dipole as there are people with minds that like to experiment. Most variations work very well, unlike some antenna designs that are ultra-critical in their design parameters.
Long live the dipole!
