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.

Power has nothing to do with SWR, it's a function of the transmission
line/antenna.
