Foundations Of Amateur Radio

Foundations of Amateur Radio The way we connect our antenna to our radio depends on a number of different factors. If you've come through the ranks recently, like I have, it's probable that you've only ever considered using COAXIAL cable. It's a single conductor, surrounded by some type of insulator, which in turn is surrounded by a conductive shield, which is protected by another layer. There are variations where the shield has multiple layers, including layers of foil and braid, so-called quad-shield COAX, and there are variants that have several cores, sometimes two sets of COAX connected side-by-side and so on. In many ways, COAX is an invention of convenience, which has several compromises as a result, loss over distance, termination issues, twisting and deformation and others. It's compact, less susceptible to external interference, it's relatively easy to route to its destination and if you treat it well, it's easy to carry around, but it's not the only way you can feed an antenna.
