I'm considering going offshore in my flats boat on calm days and figured I better take a radio because the cell phone won't work. My mother-in-law gave me her old VHF but I would need to buy an antennae. Looks like that would cost me around $60 for a 3' antennae and cheap mount. But I'm not crazy about having an antennae on a flats boat, so I looked at a few handhelds. There are several for around $100, but they say they are only good for five miles. That seems kinda short. Is anybody using a handheld getting over 5 miles?
