Foundations Of Amateur Radio

Foundations of Amateur Radio Beauty is in the eye of the beholder. I look at an antenna and marvel at what it implies. A simple piece of conducting material made into some particular shape and size that harnesses the radio spectrum. I find it fascinating that this can and does exist and my fascination translates into a thing of beauty. I recall being on a camping trip and being introduced by a friend to an antenna that was strung between two trees in the middle of the bush. For some reason that escapes me we needed to lower the antenna and I got to have a look at the feed-point. Let me describe this to you. Picture a ceramic fence insulator. The two legs of the wire dipole are each fed through the insulator at a 90 degree offset, in just the same way as you would install it into an electric fence. Looped around this is a piece of RG213 coax which is soldered onto each leg of the dipole, shield to one side, centre to the other. No traditional balun, but there is a piece of wire wrapped around the coax, ho
