A fully automatic 1kW antenna tuner that matches 3061 and 3062 amplifiers to wire and whip antennas across the 2 to 30 MHz band, sustaining full duty cycle power for land and sea HF operations.
Tuned in seconds. Held on near-zero draw. A highly optimised tuning algorithm matches new frequencies in under five seconds, with previously tuned frequencies recalled near instantly from memory. Custom-designed latching relays hold the match once tuned and draw minimal power during operation, lowering noise and protecting long-term reliability across extended deployments. The 3240 HF Antenna Tuner brings rapid connectivity to teams when it matters most.
One tuner, sized for the whole HF chain. The 3240 HF Antenna Tuner directly interfaces with the 3061 and 3062 HF power amplifiers, making it, compatible with the NGT, Envoy, and Sentry-H transceivers already in the field. Able to run attended or remote, the 3240 can run over distances up to 100 m, enabling co-location, tactical security, and providing unmatched in-field tactical advantage.
Built for the deck and the desert. The 3240 HF Antenna Tuner is sealed to IP66 in a welded aluminium housing that holds 1 kW PEP and average power at full duty cycle for both voice and data, across an operational range of -20 °C to +55 °C. Marine-grade paint, available in haze grey, desert sand, or white, enables tactical camouflage whilst resisting salt and sun damage. Low current latching relays add no heat load once the match is held, protecting reliability through sustained transmit cycles. This is a high-power HF antenna tuner qualified for the conditions a HF programme actually operates in.
1 kW PEP and average. Full duty cycle voice and data across 2 to 30 MHz.
New frequencies matched in under 5 seconds typical. 3G ALE and frequency hopping compatible.
Tunes long wire from 23 to 46 m and whips from 5 to 15 m for land and sea installs.
Custom latching relays hold the match on minimal power. Low noise, long term reliability.
Welded aluminium sealed to IP66. Marine grade paint in haze grey, desert sand, or white.
3220 power supply carries power and control up to 100 m, siting the tuner away from the radio.
Direct interface with 3061 and 3062 amplifiers. NGT, Envoy, and Sentry-H compatible.
