Choosing a Digital Antenna

Strong reception keeps you connected to phones, data, and radio when you leave the dock. Digital Antenna makes cellular antennas, dual band units, and VHF antennas, along with boosters that strengthen weak cell signal. Pick the antenna that matches what you want to receive, whether that is cell data, VHF radio, or both on a single dual band mast.

Gain, Length, and Mounting

Antenna performance is shown in gain, listed in dB, and physical length such as 4 or 8 feet. Higher gain and taller antennas reach farther but need clear mounting and a steady base. Match the antenna color and mount to your boat, and confirm the connector and any deck mount fits your cable run before you order.

Frequently Asked Questions

What does antenna gain in dB mean?

Gain measures how much an antenna focuses signal toward the horizon. Higher dB reaches farther but needs a clear, steady mount. Taller antennas usually offer more gain.

Can one antenna handle both cell and VHF?

Dual band antennas cover more than one frequency range, such as cellular bands together. For VHF radio you generally want a dedicated VHF antenna unless the product lists combined coverage.

How long an antenna do I need?

Longer antennas like 8 foot models reach farther offshore, while 4 foot models suit smaller boats with limited mounting room. Match length to your range needs and mounting space.
