5.  Remove the bracket from the radio, 

and use the mounting hardware to secure the 

bracket to the mounting surface.

6.  Install the radio back into the mounting 

bracket.

To operate correctly, your radio requires two 

electrical connections: 

 x

providing it with power from the boat’s 

electrical system 

 x

connecting a VHF-FM marine antenna to the antenna connector 

Nominal 13.8 VDC power supply with a 

negative ground (10.5 VDC to 16.0 VDC). 

Power leads should be kept as short as 

possible. A direct connection to the power 

supply is ideal.

Minimum of #14 AWG copper wire for 

extensions up to 20 feet, 12 AWG wire for 

extensions from 20 to 35 feet, or 10 AWG 

wire for extensions from 35 to 60 feet.

Male PL-259 connector

50 Ω impedance

Minimum 4 foot, 3 dB rated antenna for 

sailboats or 8 foot, 6dB rated antenna for 

powerboats 

Minimum RG-58 lead-in wire for antenna 

leads up to 20 feet, RG-8X for antenna 

leads from 20 to 35 feet, or RG-8U for 

antenna leads from 35 to 60 feet.

1.  Connect the BLACK wire of the power cable to the NEGATIVE (-) side of your power 

source. 

2.  Connect the RED wire of the power cable to the 

POSITIVE (+) side of your power source. 

3.  NOTE: To extend the life of the radio, use waterproof 

tape to seal electrical connections. 

4.  Install your antenna according to the manufacturer’s 

instructions. 

5.  If necessary, consult the FCC guidelines for antenna 

separation. See Antenna Selection and Installation on 

page 

 for more details. (In summary, the FCC recommends that antennas up to 3 dB be 

installed a minimum of 3 feet from any occupied location; antennas over 3 dB should be 

installed at least 6 feet away.) 

6.  Connect the PL-259 connector from the antenna lead-in wires to the SO238 connector 

labeled 

 on the back of your radio.
