VHF Marine Antennas — 3dB to 6dB, 4ft to 8ft, AIS Combination Antennas
VHF marine antennas cover sailboats, trailerable powerboats, and offshore vessels. Short 4-foot 3dB antennas (Shakespeare QC-4-T, Scout KS-22) suit height-restricted vessels. Tall 8-foot 6dB antennas (Shakespeare QC-8-T, Phase III) maximize range for offshore use. AIS combination antennas (Shakespeare Galaxy AIS, Digital Yacht GV30) receive both VHF and AIS signals on a single feedline. All use the standard 1-inch 14-thread PL-259 base.
