[G3OJV] knows the pain of trying to operate a ham radio transmitter on a small lot. His recent video shows how to put up a workable basic HF antenna in a small backyard. The center of the system is a 49:1 unun. An unun is like a balun, but while a balun goes from balanced line to an unbalanced antenna, the unun has both sides unbalanced. You can see his explanation in the video below.
The tiny hand-size box costs well under $40 or $50 and covers the whole HF band at up to 200 W. The video shows the inside of the box which, as you’d expect, is a toroid with a few turns of wire.
The proposed antenna is an end-fed dipole fed with the unun. These are somewhat controversial with some people swearing they can’t work and others saying they are amazing. We are guessing they may not outperform a perfect antenna system, but we also know that you can have a lot of fun with almost any kind of radiator.
The element is about 33 ft long, but to make it fit, you can bend the antenna to fit your lot. Again, it is probably not optimal, but better than nothing. Erecting a wire antenna like this is easy and just requires some insulators and supporting rope or string. Using thin wire and low-profile rope, you can hide it nearly anywhere.
Does it work? Seems to in the video, at least judging by the SWR. As [G3OJV] says, why not try it before dismissing it?
