Are you experiencing more “dead zones” or areas of static than usual with your marine radio? There are several things you can do to improve the range of your radios.
Check the Antenna
The antenna is an important component to marine radio and if there’s an issue with the antenna there’s going to be an issue with your coverage and range. Check to make sure the radio’s antenna is not bent, cracked, or otherwise broken to the point that the metal coiled antenna piece is exposed. In addition, make sure the antenna is screwed on correctly to the antenna connector of the radio. If the antenna is not attached correctly or broken it’ll drastically reduce your coverage. Simply replacing an old and damaged antenna provides an effective solution.
Fresh batteries with a full charge will ensure your radio transmits as far as possible. Batteries on all rechargeable VHF marine radio that are 1.5 to 2 years old may start to degrade and therefore not hold a charge for as long. This is considered normal wear and tear. If your marine radio is not reaching the same range it once did, it might be time to check out the batteries and consider replacing them.
Just like all electronics, VHF marine radios have a shelf life and at a certain point, they become old and worn out and do not operate with the same efficiency as they once did. Radios that have peaked above 5 to 6 years old likely need to be replaced. In addition, radios that have not been serviced in a while may require some repairs to get them working in optimum order again. Radios require regular maintenance to keep them working in good condition for as long as possible.
