Support at the top and tie off the sides to maintain a square diamond shape. Connect to transceiver via antenna coupler that can handle high impedances. That's all there is to it. About the simplest gain antenna anyone could build for 10 metres - provided you have a support at least 7 or 8 metres high. It's supposed to have 3-4dB gain and a bidirectional figure 8 pattern, broadside to the wire. Did it live up to its claims? The antenna was taken to a local beach for testing. It hasn't been compared to a reference antenna and not all reports were Q5. Nevertheless seven mostly DX contacts in a session with QRP can't be bad. And this antenna, or more accurately its 20m wire, is exceptionally versatile. Join the top for a full wave loop on 20m. Unconnect one end for a 1/2 wave end-fed for 40m. In a pinch it will do as a 1/4 wave on 80m. Any other band up to 6m will tune up with a decent antenna coupler. Acknowledgement for end piece The Radio Ham by Tony Hancock.
