Has anyone mounted a VHF antenna on the mast head of a H216 (or similar boat)? Attached is the top of my mast. Would it be possible to drill a hole in the mast and run a coax cable down inside the mast to come out somewhere near the bottom?Currently I have a simple hand-held marine radio, but I was wondering what it would take to get an antenna on the mast (to increase my broadcast distance)...
