Fellow Nuckollheads,
I've been doing a lot of reading on-line concerning eliminating RFI in the
HF band in my mobile 10/11 meter installation. The current wisdom seems to
be to "ground everything" which I am in the process of doing. BUT... All the
ham gurus recommend using tinned braided wire for RF grounding in preference
to the usual copper w/ insulation "hook-up" wire. I can't figure out why
this would matter. And then, of course, the real meat of the matter... If I
do this to my SkyRanger, will it decrease RFI through my VHF Comm???

I hope that's just an 11m installation ;) But where is the RFI occurring?
I'm not sure what they are talking about re: tinned braided vs
copper, but it sounds like nonsense to me. Unless you're dealing
with high power levels and very tiny hookup wire, the RF is going to
get grounded either way. RF travels down the circumference of wire,
so larger diameters are better - to a point. You won't notice the difference.
Your VHF comm radio should already have good shielding, so going
crazy with grounds is not necessary. A single ground should
suffice. What RFI are you trying to eliminate?
