Anyone know anything about coax & vhf radios? I'm replacing the rotten old wire in the mast. RG-8x or RG-213. Is R-213 overkill for our boats? I've seen the numbers for signal loss, but it means nothing to me. I keep the radio about two feet from the galley bulkhead so i'm estimating 50 feet to the top of the mast. 1337734136.0
