The PR-422 is an Active Extra High Performance Omni-directional wide-band Terrestiral AM-FM-TV Antenna (0.1-30 and 40-860 MHz) for Maritime use where second rate efficiency is unacceptable.

The PR-422 is designed for High End Commercial and Military vessels and is based on a configuration of 3 circular dipoles coupled to a low noise amplifier via a separate broadband filter network. Maximum performance is assured through the extensive use of a Network Analyzer in the initial design and in the final construction and tuning of each unit. Microwave transistors provide needed gain with a minimum of internally generated noise. Careful engineering and the use of very high quality components yields excellent intermod performance and sharp hand tuned filters greatly reduce the chance of interferrence from outside of the TV bands.

The PR-422 is at the head of a new 4000 Series Marine Cassette
Amplifier System with ground isolated distribution passives introduced
in 1998. The Series 4000 is the result of painstaking engineering and
the use of state of the art components including high performance
GaAs Heterojunction Bipolar Transistors and MMIC devices.
