[TowerTalk] Grounding ... again...with a twist.

[Roger (K8RI)]

We've beat the single point ground right into the ground over the past few 
months, but I have a question as to a different approach.

I have two stations, one in my shop and one in the house. I have a 100' 45G 
with the big antennas on it and currently a 40' tower on the West end of the 
shop with the AV-640 vertical, and another mast on the North side of the 
shop with a 144/440 colinear vertical.  The 40' Aluminum tower will be 
replaced with 50 to 60' of 25G and most likely it'll get a small tribander.

Eventually the system will be set up (hopefully by next summer) so I will be 
able to use either antenna system from either location. Of course there is 
an extensive ground system under the big tower and a substantial one under 
the tower and mast at the shop. These ground systems tie together.

The interesting part is the shop and the house each have their own 
electrical service and underground feeds even though they both come from the 
same transformer at the road. The ground rod at the shop is not acessible 
although the cable going to it is. However by I can't tie into that cable 
according to code.

Any suggestions as to the grounding? Remember even though they have 
different power feeds both stations will be operating either antenna system. 
(possibly at the same time, just different antennas). This is essentially 
the same as two neighbors using the same antennas.
