4 SAFETY / WARNING INFORMATION This radio is restricted to occupational use, work related operations only where the radio operator must have the knowledge to control the exposure conditions of its passengers and bystanders by maintaining the minimum separation dis- tance of 0.6 m (2 feet). Failure to observe these restrictions will result in exceeding the FCC RF expo- sure limits. Antenna Installation: The antenna must be located at least 0.6 m (2 feet) away from passengers in order to comply w

7 GETTING STARTED 7.1 ABOUT VHF RADIO The radio frequencies used in the VHF marine band lie between 156 and 158 MHz with some shore stations available between 161 and 163 MHz. The ma- rine VHF band provides communications over distances that are essentially “line of sight” (VHF signals do not travel well through objects such as buildings, hills or trees). Actual transmission range depends much more on antenna type, gain and height than on the power output of the transmitter. On a fixed mount 2

7.3 COAXIAL CABLE VHF antennas are connected to the transceiver by means of a coaxial cable – a shielded transmission line. Coaxial cable is specified by it’s diameter and construction. For runs less than 20 feet, RG-58/U, about 1/4 inch in diameter is a good choice. For runs over 20 feet but less than 50 feet, the larger RG-8X or RG-213/U should be used for cable runs over 50 feet RG-8X should be used. For installa- tion of the connector onto the coaxial cable refer to the figure below. Adapte
