Marine Antennas

Match the antenna type to the radio or system (VHF, AM/FM, GPS, cellular) and choose an antenna with the correct frequency range and connector; also consider gain (higher gain for longer range), mount style (rail, mast, deck), and whether you need a fixed or fold-down design for clearance

Reception and range depend on antenna height above water, gain, frequency (VHF performs differently than MF/HF), cable quality and length (long runs increase loss), and obstructions or nearby metal on the boat

Marine antennas range from budget options under $50 for simple AM/FM or small VHF whips to mid-range and premium antennas $50–$300+ for higher-gain VHF, multiband or stainless steel models; the right price depends on features, materials, and intended use

Follow the manufacturer's mount instructions, use a recommended mount type for your surface, use the correct coax and connectors, secure the cable with drip loops, and ensure proper grounding or bonding as required for your radio system to reduce interference and static

Inspect mounts and connectors regularly for corrosion, tighten hardware, clean contacts, replace damaged coax or seals, and lubricate moving parts on fold-down mounts; stainless or plated fittings and UV-resistant materials reduce maintenance frequency

Some antennas combine functions (e.g., VHF with an embedded FM or GPS element), but combined antennas must match required frequency ranges and may require specific splitters or filters; verify compatibility before choosing a multiband unit

Use marine-grade coax (typically RG-58, RG-8X, RG-213/LMR-400 depending on run length) and corrosion-resistant PL-259/SO-239 or N-type connectors as specified by the antenna and radio; keep cable runs as short as practical to minimize signal loss
