One time for a 160 meter tee vertical I made a grounding plate out of soft copper water tubing that would be used for an ice make in a refrigerator. I shaped it into a ring and soldered 64 radials to
I tried that method in Colorado and found that with time the loops would become loose due to endless expansion and contraction of the metals due to the large temperature swings that occurred at groun
I've done extensive experimentation with radials on vertical antennas on 160 meters during the past 18 years. Back in 2001 a MF broadcast engineer friend of mine using professional broadcast measurin

.....I don't know where the 120 figure came from, but I never stated that as an absolute requirement...... The 120 radial concept came directly from the FCC or I guess at the time the FRC. My recolle
If installed over salty marsh. Ever tried to model or compare any vertical over average and "perfect" sea ground and see the gain at LOW angles? Speaking of low angles, when it comes to 160 meter ver
The half wave inverted L is another good elevated performer sans radials. Just bring the feedline at right angles to the L. (as close as possible) I am wondering why hams like AA4NN get good results

A number of years ago here in Florida I had a ham friend that experimented with using his screened pool lanai as an antenna and his pool as the ground. Lightning struck a power pole nearby and allot
