Fixed Antenna Mounts

What Are Fixed Antenna Mounts?

A fixed antenna mount is the hardware foundation that keeps your marine or RV antenna locked in position — and its importance is easy to underestimate. Whether you rely on a VHF radio for distress calling, a GPS antenna for chartplotter accuracy, or an AIS receiver for collision awareness, none of that technology performs reliably without a secure, properly positioned mount beneath it.

Choosing the right antenna mount is equally as important as selecting the right antenna to ensure reliable communications and avoid damage to either the antenna or vessel. A fixed mount — as opposed to a ratchet or adjustable style — holds the antenna in a permanently upright, stable position. With its strong, fixed position, your antenna is guaranteed to stay in the perfect position, meaning no interruption of data.

Common Applications

Fixed antenna mounts serve a wide range of communication and navigation systems on the water and on the road. Marine VHF antennas support distress calling, marina contact, bridge communication, and boat-to-boat radio use; AIS antennas support vessel tracking and collision awareness; GPS antennas help chartplotters maintain position data; and AM/FM or TV antennas improve onboard entertainment reception. On RVs, fixed mounts anchor cellular, Wi-Fi, and GPS antennas to rooftops and exterior walls for consistent connectivity on the go.

Key Considerations When Choosing a Fixed Antenna Mount

• Material: Marine antenna mounts are designed to withstand the rigors of outdoor use and may offer better performance and longevity compared to standard mounts. Look for stainless steel or marine-grade composite construction to resist corrosion in saltwater environments.
• Mounting Surface: A flange mount is the simplest type of marine mount — it bolts to the deck or other level surface. Consider your boat's layout and whether you need a deck, bulkhead, rail, or transom-style base.
• Thread Compatibility: Most standard antenna bases use a 1"-14 TPI thread. Confirm your antenna's base thread matches the mount before purchasing.
• Cable Management: Many Shakespeare® mounts include a special cable slot that eliminates removal of most factory-installed connectors, making installation cleaner and easier.
• Height and Clearance: Where to place your antenna is a balancing act — the outside antenna will need to be mounted high enough to pick up signal from distant towers, and the higher you can mount it, the better reception you'll get.
