:said by BosstonesOwn :Out of curiosity exactly how far can a vhf wave travel ? I just bought a new boat and it has a vhf radio with the gps beacon signal tied in. I am sort of curious of exactly how far that sucker can broadcast.
Ok back on topic after the answer
The reason they tell you the numbers they tell you is because planning must be absolute. If you want to calculate your range with VHF just figure the using this link:

www.qsl.net/w4sat/horizon.htmThis as I said is because safety is an issue. The truth is your range will nearly always be greater than that returned by that calculator over water because ducting is very common over water. It is nearly always present.
Neat they told us 7 miles max. From the high of the antenna to the water is 15 feet on #1 and 12 on #2 , really interesting I have never dealt with vhf before. I usually carry a sat phone from work. But it looks like im in the market for a nice vhf antenna that may be telescopic
