Digital Yacht CX4A Commercial AIS/VHF Antenna

The Digital Yacht CX4A Commercial AIS/VHF Antenna is a commercial-grade antenna tuned for AIS to give you maximum AIS range. It is a high-quality glass reinforced plastic (GRP) antenna 4 ft long. It is aimed at professional vessels and super yacht installations.

A dedicated AIS antenna mounted high gives the best range for both receiving other vessels and transmitting your own position. Because it is tuned to the AIS frequencies, it performs better for AIS than a general VHF antenna. Its heavy GRP build suits boats that run offshore and need gear that lasts.

Digital Yacht recommends low-loss 50 ohm coax such as RG-213, not supplied, for the best performance. That matters most on long cable runs from a mast or arch down to the AIS unit, where thinner cable loses signal. Check that your boat has the commercial-style fixing base this antenna needs before ordering. Other antennas are in our marine antennas section.
