Install Check

Confirm antenna type, connector, cable length, mount thread, fold-down clearance, device compatibility, and installation height before ordering.

Ask Parts Desk

Signal problems often come from the full installation path, not just the antenna. Check the antenna, mount, coax, connectors, cable run, and surrounding interference.

Find Antennas & Mounts Faster

Search by Signal Type, Mount Style, Connector, Cable, or Brand

Start with the device the antenna supports: VHF, AIS, GPS, radar, cellular, Wi-Fi, satellite, or chartplotter. Then match the mount style, cable length, connector type, and installation location.

Communication & Awareness

VHF and AIS Need the Right Antenna Path

VHF and AIS performance depends on antenna height, coax condition, connector quality, and clean installation. Match the antenna to the radio or AIS equipment and choose the mount around the boat layout.

Navigation & Electronics

GPS, Radar, and Data Antennas Complete the Helm

GPS antennas, radar mounts, cellular antennas, Wi-Fi antennas, and satellite hardware should be planned with the chartplotter, radar, AIS, network, and power system.

GPS MountsRadar MountsCellular & Wi-Fi
01

Match the Signal

VHF, AIS, GPS, radar, Wi-Fi, cellular, and satellite antennas are not interchangeable. Match the antenna to the equipment.

02

Choose the Mount

Confirm ratchet, rail, deck, mast, hardtop, wedge, or extension mounting based on clearance, height, and access.

03

Check the Cable

Long cable runs, damaged coax, poor connectors, water intrusion, and tight bends can reduce signal performance.

Installation Help

Reception Problems Are Often Installation Problems

If communication or positioning is weak, inspect the entire path from antenna to device. The antenna, mount, coax, connector, cable length, installation height, and nearby metal or electronics can all affect performance.

Antennas & Mounts FAQ

Choosing Marine Antennas and Mounts

Can I use the same antenna for VHF, AIS, and GPS?

No. VHF, AIS, and GPS use different signal requirements. Some installations can use splitters or shared equipment, but compatibility must be confirmed.

What should I check before buying an antenna mount?

Confirm mount thread, rail or deck size, backing support, fold-down clearance, installation angle, cable entry, and antenna load.

Why does cable quality matter?

Damaged coax, poor connectors, water intrusion, and long cable runs can reduce performance even when the antenna is correct.

Can the Parts Desk help match antenna hardware?

Yes. Send the equipment model, antenna type, current mount photos, connector type, cable length, and installation location.
