- Cheap antenna to make from 160m - 6m
pop
- The antenna is nothing more than a simple 2.4 metre square loop drawing pinned to the internal brick wall of the spare bedroom. Yep, thats right, the inside wall of the spare bedroom - ideal for flat dwellers, hotel rooms or whinging neighbours, The loop has a simple switched inductance at the top of the square loop and uses a simple coaxial stub to tune the antenna. An additional variable capacitor placed across the feedpoint can be used to fine tune the resonance of the antenna, by Andy G0FTD
