Power Supply Requirements VHF Antenna Requirements
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.
