My 80/160 GP doesn't seem to need much matching, or with a feed Z around 
35 ohms on 80 I'm just too lazy. The amps load fine at the far end of 
300 ft of coax. So I wound a 85mH coil installed from feed to gnd to 
solve the static deal. 85mH had no effect on feed Z as measured both 
with a Autek VA-1 (at the ant) and observed at the shack. 85mH isn't 
much - probably like none - lightning protection but does bleed off the 
static.
