Tuners

Our range of tuners has been selected to offer quality, performance and ease of use.

A tuner, antenna coupler or tuning box, is a device used to protect your radio transmitter in the event of excessively high SWR and to improve reception. It allows you to use a multiband antenna on different frequency bands.

The tuner adjusts the impedance of the antenna's coaxial line to match that of the transmitter (50 ohms), thus reducing the SWR to an acceptable value for the set and protecting it from excessive power feedback to the transmitter.

By adjusting the tuning, the tuner also improves the signal reception level.

To choose a tuning box, identify the type of antenna (long wire, vertical, mobile, etc.) to define the best compatible tuner, depending on use and frequency coverage required.

Make sure the tuner can handle your transmitter's output power to avoid damage.

Some tuners offer features such as memory settings for specific frequencies.

Check wiring and connections regularly to ensure optimum performance of your tuner.
