You really want the corrent impedance coax. Check your radio specs, it
probably calls for 50 ohm cable.

RG-6, 58, or 59 means diddily at VHF frequencies. All will work

Sure they'll all "work". But for the most efficient system you should
match the coax impedance to radio input/output. It "does" make a
difference.


I agree with you. But at the level you are talking about, you'd be better
off getting a SWR meter and trim your antenna to the best SWR average over
the marine VHF bandwidth. The difference, at 25 watts, will be minimal at
best, even after that.
