Pacific Aerials P6122 2.5m VHF UltraGlass Antenna

Pacific Aerials SeaMaster Pro 2.5m VHF Collinear UltraGlass Antenna

The Pacific Aerials P6122 is a high-gain, long-range 2.5-meter (8.2 ft) collinear marine VHF antenna engineered for offshore vessels, commercial fishing boats, and larger motor yachts requiring maximum communication range. As part of the quick-demountable SeaMaster Pro Series, the P6122 features a cableless base connection that screws directly onto SeaMaster Pro mounts. This modular design allows the large 2.5m whip to be unscrewed in seconds for trailering, winter storage, or overhead clearance without disturbing hardwired coaxial runs.

Featuring a high-performance collinear internal element (6 dBi gain / 9 dB Marine Gain), the P6122 flattens the radiation pattern toward the horizon to deliver superior long-distance transmission and reception over rough open water. Enclosed in a heavy-duty UltraGlass composite radome with a corrosion-proof glass-filled nylon ferrule, the antenna is built to withstand high wind loads, saltwater spray, and intense UV exposure.

Key Features

• High-Gain Collinear Array: 6 dBi gain (9 dB Marine Gain) compresses signal trajectory toward the horizon for long-range offshore VHF performance.

• SeaMaster Pro Cableless Design: Unthreads quickly from the base mount without twisting or pulling coaxial cables.

• UltraGlass Composite Construction: Rigid, heavy-duty glass fiber radome prevents flex fatigue and resists UV breakdown.

• Corrosion-Proof Glass-Filled Nylon Ferrule: Molded nylon threads eliminate metal-on-metal galling, rust, and thread binding.

• Ground-Plane Independent: Maintains optimum RF radiation efficiency across fiberglass, composite, aluminum, and steel vessel hulls.
