RH6221-125W

Meeting MIL-STD-810 for shock and vibration, the fully weatherproof, fully immersible RH6221 ensures rapid link establishment and the highest level of communication reliability, under any operational condition.

 

The RH6221  provide users with essential benefits and features

Fast, automatic link establishment

  • The RH6221  automatically seek the optimum tuning point at all communication conditions.
  • An embedded memory facility automatically stores any configuration required to tune to a specific frequency. Whenever that frequency is called on subsequent uses, the RH6221  quickly reconfigure to the required frequency. Whenever variations affect communication quality, the RH6221  automatically re-tune the antenna to optimize signal quality.

Highly reliable HF radio communications

  • Utilizing advanced microprocessor-controlled technology, the RH6221  provide precise and continuous tuning over the entire 1.6-30 MHz operating spectrum.

User-friendliness

The RH6221  can quickly and easily be mounted to a wide variety of vehicles, requiring no drilling, no special fitting nor special tools.
