I've developed a High Z Antenna Amplifier for 160m and other HF use as previously mentioned on the list. Usually these would be used with a ground rod and 5m vertical element. With the lockdown it's
Reminiscent of the DDRR antenna? 73, Roy K6XK Iowa Usually these would be used with a ground rod and 5m vertical element. With the lockdown it's not possible to nip to the shops for a ground ro
Your "loop ground" made me recall the US military "surface wire ground", Chris, which was (is?) used for mobile applications, and is often configured as a loop of wire, held down by metallic stakes,
The usual kind of field produces radial currents, and that's why we use radial wires. But what kind of field would make the current run in circles? Or is it that the only effective piece of wire is t
Chicken wire laid on the ground makes an excellent RF ground for Beverages and other antennas requiring a good RF ground. 73 Frank W3LPL -- Original Message -- Your "loop ground" made me recall the U
Without more detail of your system, the cause is only a guess. Here are some possibilities. A single wire isn't much of a ground plane. It will make a vertical directional. When you change from a sin
Another thought. Changing to a good ground system with a good choke at the antenna feedpoint will make your vertical omnidirectional, but that may not solve the noise problem,. You may need a directi
Greetings All, It seems this discussion has morphed into a discussion on ground planes for regular vertical antennas where if I read the authors description correctly he is using a Hi-Z amplifier. Th
