Ham radio ground loop
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. WebA counterpoise is simply a long, insulated wire that attaches to the ground connection on your antenna tuner. The best counterpoise is 1/4-wavelength at the lowest frequency you intend to use. That’s a lot of wire at, say, 3.5 MHz, but you can loop the wire around the room and hide it from view.

WebFigure 2 shows a grounding diagram of a typical ham station. There is a heavy ground strap running along the back of the equipment. The ground strap eventually reaches the earth ground system, a ground rod, through a heavy gauge copper wire 11 feet in length. WebApr 5, 2024 · If a large horizontal loop antenna, insulated but laying at ground level, works as an MF and low HF receive antenna, why (even though it has very high ground losses) can't it be used for transmit (to the stations it can hear) via the reciprocity theorem? antenna antenna-theory propagation Share Improve this question Follow
WebA traveling-wave antenna offers some attractive qualities for your station: 50 ohm feedpoint at ground level, no tuner required, horizontal and vertical radiation components, no radials, nothing in the air but wire, and flexible size and height requirements.
