I question if I have created a ground loop problem between the AC ground and a vertical antenna radial system that may be causing some RFI.
My AC safety ground consists of two 8' rods one vertical, one horizontal driven into the earth. The horizontal one is several feet below grade and both are nearby the breaker panel.
The radial system for the transmit antenna is made from thirty, 60ft long #12 radials fanned out in a semicircle.
My receive antenna is comprised of two ground independent pennant antennas galvanicaly isolated from the coax feedlines via transformer. The coax outer braid however is common with the radial system at its center. Coax from both antenna systems runs about 90ft on top of the ground to receiver and transmitter.
There is no direct connection between the radial system and AC ground except through the coax outer braid as they connect to the transmitter and receiver while both receiver and transmitter are AC grounded. This seems to me to create a large loop. Should I connect the radial system to AC ground directly and if I did, should I connect to the center point or just extend one radial to make connection?
