WebThis a wire loop receive antenna placed directly on the ground. Its great advantage is that you can't see it The loop is made from insulated wire laid directly on the ground and fed at one corner with a 400 to 50 Ohm broadband isolating transformer Maximum directivity is at right angles to the feed point.

Webmost backyard antennas, the average ham is lucky to achieve an antenna height of 1 wavelength on 10 meters, while the truly fortunate operator may get his wire to 1 wavelength on 17 or 20 meters. Every horizontal antenna is subject to essentially the same general phenomena that affect horizontal dipoles in terms of their height above ground.
