Let’s Talk VHF!!
Just what are some of the capabilities and characteristics of a VHF Radio? These radios are available in fixed units, hand held units, and submersible units. It is not out of the question to have more than one onboard. VHF Radios require minimal power to transmit. The lower power should be used whenever possible as all units have the capability of transmitting on either 1 Watt or 2 Watts.
Most VHF sets only allow only one person at a time to talk, unlike the cell phone you probably have on your hip. When transmitting, the user must depress a “transmit button” on the microphone. This process of only one at a time talking is called simplex. Duplex sets are also available, but usually are much more expensive.
When mounting your VHF antenna, it is advisable to mount it has high as possible since VHF radio waves travel in a straight line.
