Marine Antenna Installation Guide

Installation Instructions for the Wilson Electronics Marine Antenna (301130)

Antenna Adapter Required – Sold Separately

A phone/data card-specific Antenna Adapter is required when connecting the antenna directly to a cell phone or laptop data card. Adapter type may vary depending on cell phone or laptop data card. To identify the correct adapter, check our web site or contact us.

Before You Install

Please read all instructions before installing and check the parts supplied against those listed in this guide. Wilson’s weatherproof fiberglass-encased antenna is omni-directional and ideal for many marine applications including small boats, cabin cruisers and yachts as well as RVs, offices and homes. It has the highest gain allowed for a mobile antenna and has a built-in radial ground plane for maximum performance.

Wilson's innovative design results in high efficiency and low signal loss, which means more signal to your cell phone or cellular data card. This performance-based marine antenna is backed by Wilson’s 30-day money-back guarantee and 1-year warranty.

Carefully Determine Your Mounting Location

The Wilson® Marine Antenna should be mounted as high as possible with no obstructions. Marine antennas work on a “line-of-sight” basis, so the higher your antenna is, the farther it can receive a signal. This gives you a greater range for your cellular communications.

There is a compromise between installing the antenna as high as possible and keeping the cable run short to reduce signal loss. For cable runs under 20 feet (recommended), we stock various RG-58 cable lengths and connectors available (sold separately).

If cable length over 20 feet is needed, we recommend increasing the cable size to Wilson 400 (LMR-400 type) cable to reduce signal loss. Make sure your mounting location is as far away as possible from other antennas and upright objects like masts. Be careful not to kink or crush the antenna cable or bend it tightly around obstructions during installation. This can lead to poor performance and signal loss.

Vertical Placement

Vertical placement is very important for proper operation. There may be a desire to angle the antenna backwards for aesthetic reasons. However, not having the antenna mounted vertically decreases its performance. A general “rule of thumb” for placement is to install all antennas at least an antenna’s length away from other antennas. If there is not enough separation between antennas (especially when using a wireless signal amplifier), then oscillation may occur causing the amplifier to power down.

Assembling and Attaching the Antenna

Screw the six radials into the holes near the base of the antenna (see diagram). Note: The hole size is different between the short and long radials. Tighten the radials snugly with a wrench. Do NOT over tighten. The included liquid thread lock must be used to ensure the radials do not vibrate loose.

Use the 1” 14-thread coupler (included) to attach the antenna to any standard marine mounting bracket. The coupler provides a feed through for routing the connecting cable, which will run to your cell phone, cellular data card, or Wilson signal amplifier.

Once the antenna is properly attached to the mounting bracket, attach the connecting cable (sold separately) to the antenna’s 7” pigtail cable and route it to the location of your cell phone or cellular data card. Use the appropriate adapter for your cell phone or data card (sold separately). If you are using a Wilson Signal Amplifier, carefully follow the instructions included with the model purchased.

Warning: Damage will occur to the cable when the antenna is attached to the coupler if the cable is not allowed to turn freely.
