The Moonraker Marine-500 is a high-gain, high-performance flexible VHF marine antenna — the top of the Moonraker marine antenna range. With an impressive 6.5 dBi gain and 100W power handling, it delivers maximum range for VHF marine band communications across 156–163 MHz. Fully weatherproof and waterproof, it clamps directly to an existing mast of 30–40mm diameter — mast clamps are included. At 225cm long and just 500g, it's a lightweight yet high-performing antenna for vessels where range is a priority. Connects via SO-239 (UHF-Female).
