[TowerTalk] Antenna to Shack Ground Connection

[David Gilbert]

I don't have the expertise to be sure about it, but it always seemed to 
me that it would be best to run the ground wire (grounded at both ends 
and maybe a few places in between) in the same trench as the coax ... 
but some distance above them ... in order to provide a sort of shielding 
effect for the coax against induced currents from nearby lighting 
bursts.  I was once told that the electric utilities run a ground line 
at the top of utility poles above the actual power lines for a similar 
purpose.

Possibly induced currents in the ground wire would still couple to the 
coax anyway, but I certainly don't see how running the ground wire with 
the coax would be any worse than running them separately.

Is it preferable to run the ground connection between the two along with signal cables?  Or is it better to run the grounding connection not so close to the signal cables?  I've seen people do it both ways, and can see a possible benefit either way, but a lightning strike could throw either idea out the window.
