Re: All well and good, but
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  Based on my experience and what most people will tell you at the USPS or USCG it's about 15 miles ship to ship but can be as much as 50 miles if both antennas are high enough. See... »www.yachtcom.co.uk/comms/
But alot of it has to do with the height of the antenna and sea conditions (rolling the ship/antenna).

Here's more from the USCG...
»www.navcen.uscg.gov/marcomms/boater.htm
"Your VHF radio is intended mainly for short range communications, generally 5-10 miles, and at least 20 miles to a USCG station. To communicate at longer ranges, you will normally need a satellite telephone or an MF/HF marine radiotelephone. Marine radiotelephone equipment normally operates between 2 - 26 MHz using single sideband emissions. MF/HF marine radiotelephones can also be used to receive high seas weather broadcasts, and by using a computer and a special interface provided by some coast stations, can provide Internet email." |
