I am going to add a fix-mounted VHF radio in my boat. I would like to
know whether I should get a 3dB 3-ft antenna or a 6dB 8-ft antenna to mount on the T-top. My questions a - Books and people in this newsgroup recommend 6dB 8-ft antenna for a small powered boat. This sounds good. But I am wondering whether a 8-ft antenna is too large for my 18-ft boat. Will this make the boat "look" very top-heavy? Do people really use a 8-ft antenna in a small boat like mine? - The other alternative is a 3dB 3-ft antenna and accepting the reduced range. Does a 3dB antenna provide a good enough range given the fact that I won't go too far away from the shore (because the boat is considered as a "bay boat")? - According to post in this newsgroup, we need a metal plate for grounding if we use a 3dB antenna, and a fiberglass boat doesn't have it. My boat is a fiberglass boat. What's the alternative? Does this mean that I cannot use 3dB antenna? Thanks for any info in advance. Jay Chan |
