VHF and Antenna
I'm thinking of installing a VHF Radio and Antenna on my 28. Where have you guys mounted them as well as the antenna?
This boat is definately going on the big lake - Michigan and with only one engine, I think it would be smart to have communications.....
Anyone have a couple pictures of the radio and antenna mount locations?
Can you tell I'm getting restless to work on the boat? Only 5 more days until I can get it out of storage!!!

Re: VHF and Antenna
Whats the range? I guess I should research it. I just thought a 25W fix mount unit would be better, one less thing to haul around, but you have a good point.

Re: VHF and Antenna
Here's what I found:
Fixed-Mount VHF Radios:
VHF radios are available in both fixed-mount and hand-held models. All fixed-mount VHFs have a maximum output of 25 watts, the maximum allowed by the FCC. VHF is a line-of-sight system, which means the radio waves won't bend to follow the curvature of the earth. The VHF antenna must "see" the antenna of a distant station. Therefore, antenna height is more important in determining range than radio wattage. The effective useful range of a VHF radio is 20-25 miles.
Hand-Held VHF Radios:
VHF handhelds also offer many of the same features found on fixed-mount units. They offer portability in the same way a cordless phone allows more mobility at home. A handheld radio may be just what you need for use in a dinghy, small boat without electrical systems, or as an emergency backup for your boat's radio. Handhelds have a maximum output of six watts. Due to their short antennas, they have a limited range of five miles.
A significant increase in range can be achieved by connecting an external antenna or using a telescoping antenna mounted to the hand-held radio. Battery life varies with the size of the battery pack. Many models have optional battery packs with longer operating times, or greater transmitting power, or both. Some have battery saver circuits that turn off the receiver to save power. The battery life of a handheld can be increased by switching from full transmit power to one watt of transmit power. Handhelds are not DSC capable.
5 Miles may be enough....maybe I'll post on the main board and see what people are using.

Re: VHF and Antenna
I prefer the stainless steel half wave antenna to the 10 foot white one.

Re: VHF and Antenna
I didn't feel like drilling any holes in my Sutphen to mount the antenna, so I opted for the suction cup 18 incher. I'll only use my VHF for emergency, and if I need more range, I can hold the thing over my head.
