Because of significant ground-level blockage/multipath of my local OTA ATSC broadcast towers (all of them UHF), I installed the Antennas Direct DB2 antenna on the top of my roof using their 18" mount. This has provided an ample and pretty clean signal for input into a splitter/amplifier in my basement.
Anyway, I need to ground this antenna installation. My problem is that for line-of-sight I had to place the antenna on the side of the house opposite of where my home ground is located. To connect the antenna to the home ground I'd have to use about 80' of wire for each ground conductor, while if I put in a new ground rod on the other side of the house I'd only have 18' to 20' per wire. (If I do the latter, what gauge/type of wire should I get? I assume it can be insulated to reduce corrosion.)
So even if not optimum, will it work for me to drive down a new grounding rod and connect to that? That is, is this better or worse than nothing? I continue to read the very strong admonition to use the house ground if at all possible, with no explanation why (go ahead and get technical!)
Another question is that my coax directly enters the attic right at the antenna base. Obviously I need to put in a coax antenna discharge unit (or whatever they are called) pretty much right at the antenna. I find very little discussion as to where to get these or what brand(s) to consider, and how much they may attenuate the signal. Recommendations here wanted.
Btw, I live in Utah with very clay-like soil, so what is recommended for a grounding rod (or whatever) should I put a second one in?
Thanks in advance!
