Marine Antenna Cables

A VHF radio is one of the most important pieces of communication and safety equipment on your boat, so you want to be sure it performs properly at all times. The type and quality of a cable you use have a big impact on the performance of your antenna setup. Cables can degrade and crack over the years and connectors can corrode, compromising signal transmission. Make sure your AIS and VHF radio installations are done properly with marine antenna cables of the right type, size, and impedance.

A coaxial cable, or coax, transmits radio frequency (RF) signals between the radio and antenna with minimum possible loss. There are many types of coax cables used for different applications, but those designed to comply with the power, impedance, and frequency specs of VHF are typically limited to the following options: RG-58U, RG-8X, RG-213, and LMR400. There's a strong correlation between the wire diameter and signal loss, so it's better to run a larger cable to maintain signal strength and reduce energy loss to a minimum, especially in long-cable installations. Whatever your on-board connectivity system setup, we have the correct cables to ensure its reliability, sourced from reputable brand names such as Garmin, Icom, Ancor, and more.
