I'm still doing the ground work to get my station up and running. Right
now I'm taking care of the grounding situation....pretty important in the
lightning capitol of the US.
I'm doing the usual...grounding the bulkhead, everything to a common
ground , Polyphasers etc. One unusual aspect of my station is I have a metal
roof, actually two of them. A cupola, and then down below that is the main
metal roof. It would take some time, but it would not be a big deal to
ground the cupola to the main roof and then ground the roof to main ground
where the telco/power company ground located and tied to the bulkhead.
The roof is a standing seam type so oxidation from weathering on the
screws won't be an issue. There are thousands of screws holding the thing
together so I can't do any kind of retrofit or anything like that. Just a
stainless screw with a stainless washer holding the braid to a panel and then
down to the ground.
Anybody out there with some technical info on whether the grounding is
necessary to keep the roof at the same potential to everything else.
Also before I even got any towers up last summer, we got nailed with a
lightning hit that came through the Direct TV and took out our 60 inch screen
which was two days old. Any place to get a Polyphaser for this that won't
break the bank? I believe Direct uses around 1.2 gHz.
As always thanks for the help. I bet I get a usable answer in an
TowerTalk mailing list
