RT Family

Tactical communication products that work with any radio; providing secure digital capabilities

The RT Product Family enhances critical HF and VHF/UHF radio communications for the last mile user with cutting edge digital capabilities that include secure digital voice, situational awareness, tracking, email and chat. RT devices provide unsurpassed performance, well beyond the line of sight (BLOS), in severely degraded conditions.

The family includes Secure Digital Voice encryptors encompassing ultra-robust (300 to 2400 bps) TWELP vocoders and AES-256 encryption, suitable for HF (BLOS) and VHF/UHF radio links.

RT Devices are complimented by our CommandPoint application software (desktop, laptop and tablet) for BLOS position tracking, situational awareness and blue force tracking over HF and VHF/UHF radio links; as well as MessagePoint application software (desktop and laptop) for email and chat over HF and VHF/UHF radio links using STANAG 4538 HDL, LDL and RDL packet data modems.

Our tactical RT products provide secure and reliable communication capabilities, with units designed for handheld, manpack and base.
