Simple Ham Radio Antennas

  How would you like to have the gain of a half-square antenna applied to 4 HF bands rather than just one?   In this video, Peter Waters (G3OJV) converts a "normal" monoband half-square HF antenna to a low noise, 3dB gain antenna covering 4 Amateur Radio HF bands. Peter's modification is small enought to fit on a small urban lot or into a small garden space in your backyard. Construction is simple, using readily available materials.

Here are some observations from Peter (G3OJV): The Half-Square Antenna offers up to 3dB gain on one band. But, Peter G3OJV explains how you can add three more bands.

  Loop antennas are cheap, easy-to-build, and fairly quiet.  Properly designed, a delta loop antenna can cover several amateur radio bands. In this video, Callum (M0MCX), discusses the design, construction techniques, and benefits of using a horizontal delta loop antenna.   This antenna design is ideal for NVIS (Near Vertical Incident Skywave) service covering several hundred miles/kilometers.  The horizontal delta loop is an inexpensive antenna for local, regional, and state-wide nets.

Here are some comments from Callum (M0MCX): I am about to install a Multi-Band loop which will be resonant on 40m, 20m, 15m and 10m. It needs a 4:1 balun - but other than this balun, this is cheap to build and is well within the possibilities of many small ham radio stations. It wi...
