VHF Marine Radios
A VHF marine radio is one of the most important safety tools on any vessel. It connects you to the Coast Guard on Channel 16, enables DSC distress calls that can transmit your GPS position automatically, and keeps you connected to marinas, bridge tenders, and other vessels.
Fixed-mount radios in our catalog are designed for dependable communication and stronger range when paired with the right antenna.
Fixed Mount VHF Radios
Permanently installed 25W radios, typically paired with a roof- or mast-mounted antenna for maximum range. Many models support DSC and GPS integration.

Marine Antennas
Your VHF radio performance depends heavily on antenna quality and mounting height. A properly matched marine antenna can improve communication range and reliability.
- 4-foot 3dB antennas: Good for sailboats and boats that roll or pitch more heavily.
- 8-foot 6dB antennas: Better for many powerboats where maximum horizon range is the priority.
- AIS combo antennas: Support both VHF voice and AIS functions in one setup.
Marine Optics & Binoculars
Marine binoculars are built for wet conditions, glare, and distance viewing on open water. Waterproof construction and clear optics matter more than gimmicks.
