Hello Lowfers ! In one of the recent postings it was stated,that chicken wire on the ground makes no good RF-ground.Well what i got to say about it is not very much scientifically researched by mysel

The comments on ground systems are very interesting and I have some contributions: For a single vertical LF transmitting antenna, the most natural path for a radiating current is perfectly radial to

Hi all, I missed one other piece of information, which is now added: Kevin ZL4MD uses link coupling from his LF transmitter, which isolates the RF output, so there is no path for the mains (safety) e

From Johan, SM6LKM Connecting the mains earth to the RF earth INCREASED THE RF RESISTANCE OF THE ANTENNA. We re-checked several times, and also checked that the voltage across the capacitor was low (

I (and others) experienced the same. I think that this increase could be explained by the fact that the 'returning' current coming from the 'radial-earth' and from the 'mains-earth' have different ph

I have been a bit out of the circuit the last couple of days regarding this thread. Yours seems a very thorough investigation. Please excuse me if I revert to my MW BC experience. At a number of inst

Just a minor comment on this much discussed topic. A few years ago, when experimenting with toroidal antennas on top band, I ran into the same problem. The local field from a toroid is entirely elect

Dear all. In my experience, as in all amateur installations, you have to experiment to get the best result! At home in the city, on good clay soil, earth stakes didn't seem to help much but radials d
