4) What do you like other than the cheap white crap for antenna cable? I
used Belden 9913 (solid center conductor) on Swee****er. Is that still a
good choice?


RG214 or similar which is silver plated Cu in both conductor and
shield. Raw copper will in time oxidize and deteriorate in the salty
environment. I have seen some really ugly cables after only 5-6 years.

Common RG-58A (the white crap) looses 7.4dB/100 ft at 200MHz. That's
over half your signal used to heat the coax! RG-8X (mini-RG8 - the other
white crap) is almost as bad at 5.4 dB/100'. Belden 9913 is excellent at
only 1.8dB/100. RG-214 has 3.3dB loss/100' but as Marcus suggests may
have better corrosion resistance. Of course if money, size and weight
are unimportant there's LDF5 (c:
