I concur with most of what has been said. My main point
would be to use buss bars of some type (flat bar/plate or
copper pipe as someone mentioned .. I use plate) rather than
using the 238 as a connection point. And remember that
bigger wire is better .. and if available, flat strapping is
even better yet.
I bring the ring ground into the shack and bolt it to a
copper plate on the wall. From there I run copper flashing
(not wire) to copper buss bars on the rear of each operating
table. All equipment grounds are run to these buss bars via
braid straps. In my case, if there is metal available on a
piece of equipment, it inherits a braid strap to the buss
bar.
For the braid straps I crimp (yellow) ring ends to both ends
and attach the buss bar end of the braid to pre-drilled
holes with SS machine screws.
In the case of racks which hold pc's, DX Cluster eqpt (pc,
rigs, tnc's), amplifiers, et al .. the aluminum sides (both
sides) of the racks are grounded to this system and all eqpt
grounds then run to the nearest available hole in the rack
side rail .. again with the same braids.
This is harder to set up, but a lot lot less messy
ultimately .. and keeps the braid runs to a relatively short
length.
Have never had a r.f. problem here .. yet.
Being an "ex-microwave-radio-tech", my experience was that
if it even had a metal "part" on it, it was grounded to the
radio site ring ground. This was often carried to
ridiculous extremes (e.g. the metal frame of a wall-mounted
bulletin board ... I often wondered about that one).
(Of course there was the time that a bulldozer outside the
building snagged the ring ground while doing some grading ..
but that's a whole other story .. and it makes you
re-examine life as you knew it.)
