I'm not hep enough with electronics to build anything much more complicated than the code practice oscillator I put together on a solderless breadboard yesterday (although I'm working on learning more) but antennas are something I can build. All mine are homebrew with the exception of the G5RV, which I bought new in the package at a ham fest for ten bucks. I figured I couldn't build one for that little since I'd have to buy at least 25 feet of window line.
