3240 1kW HF Antenna Tuner provides reliable, high performance tuned antenna solutions for land and sea deployment, at RF power levels up to 1 kW. The tuner has unlimited tune from memory capacity, and using a highly optimised tuning algorithm.

New frequencies are tuned in typically less than 5 seconds, previously tuned frequencies are tuned within 150 mS. This means that HF systems using this tuner are fully compatible with high speed linking waveforms, such as 3G ALE.

The use of custom designed latching relays ensure that power draw when tuned is minimised, contributing to long term reliability, low noise and efficient use of energy.

With 1 kW RF power handling capability, the 3240 can be used for full duty cycle data and voice, including frequency hopping, over the full 2 to 30 MHz HF band.

Antenna lengths as short as 5 m and from 10 m to 46 m are supported for 3-30 MHz and 2-30 MHz tuning ranges respectively.

The tuner has a separate rack mountable power supply unit which provides a power and control interface which will support cable lengths of up to 100 m.
