A MARINE RADIO IS ONLY AS GOOD AS ITS ANTENNA

Knowledgeable boaters realize that even the most expensive radio will perform poorly with a second rate antenna that saves money up front,but jeopardizes the welfare of those aboard. That’s why they prefer the quality,performance and reliability of Shakespeare marine antennae. From the largest seagoing ships to the smallest boat bass boats,Shakespeare antennas have held up for years and years under the worst marineconditions,always performing to their maximum design capabilities.

RELIABILITY BEGINS WITH QUALITY CONSTRUCTION

Shakespeare fiberglass antennas are built with precision,beginning with hand-soldered connections,brass and copper elements, strong mechanical joints and superior electronics. The radiator and electrical elements are then encased in an exclusive Shakespeare fiberglass radome.

TIPS ON CHOOSING THE PROPER ANTENNA

Since there are many factors that influence the selection of a proper antenna for a specific application,we encourage consultation with a localdealer,whenever possible. When this is not possible,the following tips should be considered before making a final decision.

Antenna Length Gain

Height is paramount in getting the greatest range,and encouragesthe choosing of an antenna that can be placed as high as possible on the boat. This is a rating stated in decibels (dB). Generally,the higher the gain, the greater the communicating range. However,keep in mind that the higher the gain,the more compressed the beam width becomes (see illustration). A narrow beam can cause fading in rolling seas. Small,lightweight boat boats,which roll excessively in heavy seas, normally do not use a gain rating above 6dB. The more stable the platform of a vessel,the higher the gain that can effectively be used. Powerboats: Boat sailboats: Most power boats from 16' to 25' in length use a standard 8' antenna,while bigger vessels have the option of larger antennas with more gain. Caution: be sure to allow enough lay down room forclearing low bridges or other limitations. Whichever choice is made,a sturdy mounting arrangement must be used to avoid damage to both boat and antenna. As a general rule,sailboats have a 3' - 5' antenna mounted on the masthead. Some racing enthusiasts opt for an 8' antenna mounted on the stern in the event demasting should occur. Either is acceptable. A decision should be made on personal preference.
