I too have paid attention to Jim, K9YC's advice. Nobody knows it all but he's proven to know enough to be an authority on the subject so I listen to what he has to say.
To that end, I have put in a lot of effort to have the Antennas, roof tripod and breaker box tied together with #4 solid copper wire. Antennas & Rx antennas are connected via Polyphaser to the 8' ground rod outside the shack. The #4 ground wire snakes in under the door jamb and terminates on a piece of flat stock 6" long. I drilled 8 1/4" holes in that and have SS 1/4" bolts nutted down tight and use the 8 bolts as anchor points for the equipment. I have #6 insulated copper wire attached to the K3, P3, Alpha amp, 6M amp, NCC-2 and Green Heron Controller. I yet need to ground the computer, antenna switch, HI-Z controllers and the Iota DLS-55 power supply. I also need to find the best way to ground the control wires to the rotor, the HI-Z cables and the remote coax switch. Braid is much easier to use but since things don't get moved much, I bent the copper wire to fit the device to the table and being ground wire, I like the idea of solid wire & I wanted shielded so it doesn't inadvertently touch improperly down the line and create a ground loop. I could have used coax as ground but it wouldn't bend well and would always be a PITA to deal with. One thing for sure, I like how consistent things seem to be when everything is grounded. More, I feel much safer now. 73, Gary, KA1J > Hi Lee, > > When I got my K3 I rebuilt my shack from teh ground up, starting with > the ground, with an eye to reduction of RFI.
