I toured WCFL's transmitter site in 1971. The engineer said their radial field was burried over 1' deep. MK I was looking through my old ARRL Antenna Books. The text in the "Antennas for 160m" chapte
Don't forget that historically many if not most broadcast stations, plus the legendary work of Brown, Lewis and Epstein, had their radials in farm fields and cow pastures, where anything on or near t
AM radio stations did and still do have to meet field strength readings at contour data points. (.Ground wave field strength way point readings.). Directional antennas had to be carefully maintained.
Just a remind that any tower few miles!! away needs to be detuned to avoid pattern distortion. Like cellphone towers. It is the same for 160m TX tower or arrays, every tower is an antenna on low band
Radio Lumiere in Haiti lays the radials in 2' deep trenches to foil the copper thieves. Jim - WS6X _________________ Topband Reflector Archives - http://www.contesting.com/_topband

12" down on 160 meters is identical with being on top for amateur purposes for most midwest soils. I did buried dipole signal loss measurements years back. I do not remember the exact numbers but for
When I worked on a cellular phone project in Haiti we had armed guards at each cell site to protect the generators' Diesel fuel stores and the buried copper ground wires. 73 de Gene Smar AD3F _______
I can appreciate reasons why MW BC stations and LW transmitter sites would bury their radials deeply, plus they could be expected to have the equipment and deep pockets to do it. But in my opinion, a
