Your jealous nature is so obvious. Hats for pansies. This from a guy who wears his hat backwards, with the rim in the front! Cept when the boat is moving along, then he wears it right. Proof that this NG does some good for boaters and is not all politics. I face the same issue in that I have an 8' antenna on my Tolman but recently installed a bimini and have not been sure of what to do about the antenna. Harry says his 3' antenna works fine and clears the bimini............ VHF transmission range is a function of transmitter power, receiver sensitivity, and distance to the horizon, since VHF signals propagate under normal conditions as a line-of-sight phenomenon. The way to calculate the the theoretical line-of-sight horizon distance is: distance in miles = The square root of (1.5 X the height of the antenna from the water in feet) Since the CG is normally located at the highest possible place, you shouldn't have a problem sending and receiving to them. You *will* notice the difference when you are communicating with other boats. Which could impact on the ability to get a quick response to a Pan Pan or a MayDay call. I personally think a Hard Top with an ant. mounted on the top of the Hard Top would give you better coverage, without the inconvenience of the ant. and bimini straps being in your way as you fish. If you don't have the ability to easily walk around the boat, what is the advantage of a CC? When I'm using the boat for fishing, the bimini will be down. Walking around will not be a problem. An advantage of a CC, for me, is that I prefer to operate a boat in the standing position. If I were getting the boat just for my use, I'd go with the t-top, with perhaps a three foot antenna mounted on it. But, I expect to be pulling a lot of grandkids on tubes or skis, so the wife has a big say. (in my best SWF voice) Pansy. |
