Are you good at fishing???
cuz that's what your gonna have to do if you wanna run the wire inside ur mast. Mine was already done when I bought the boat. At the top and bottom you have to fish the wire thru some kind of side hole.Bottom not that big a deal, I guess at the top is where you would feed the wire into the mast. I guess if you used some electrical wire first to run the wire down the mast, then taped or tied off the coax wire you could pull it on down. Just have the bottom of the mast lower than the top and kinda bounce the mast around, lightly of course, the wire would eventually work its way down the mast. You would be better off if you had someone to help,so one could feed or push the wire thru while the other "fishes" for it and pulls it on thru. The only other thing you have to do, is somehow figure out where that coax is going to come into the cabin.More than likely it means drilling a hole somewhere..Do you want to do that???? Not that big a deal but still....When I bought mine, that coax was an extra ten feet or so longer than my mast, so you had to feed the coax in this hole before you could really step the mast. I cut the coax and mounted a fitting on top, so now I can seperate it by undoing the fitting. Much easier to work with. Also, don't go cheap on the antenna(sp?). The difference in price's on the radios are pretty much on what all it will do and brand name. Mine was mounted in the cabin where the table is port side. Seems to be handy enough. Don't know much about the handhelds, but I've thought about getting one. For day trips, it seems it would be alot easier than goin in the cabin to make a call. Especially if I go overboard. It's gonna be a long stretch to call for help otherwise. If your handy at all you could install it. If not, I'm sure theres a fellow boater out there that would help...good luck...
