Yes, you are right on how to eonnect the cable. As far as ground loops,
some times grounding stuff causes them. Grounding everything isn't a
solve all. I've run many times without a station ground at all and
everything worked fine. As far as what type of coax, at a hundred
watts, probably doesn't matter, although something heavy like rg8 would
be better.
