Pair New REW-14 Coaxial Switches in kit witch 6pcs. new cable connectors.
For High-Power up to 900 MHz !
High quality Soviet production. Designed for Power RF applications in the
Space and Aviation devices. The switch provides extremely high reliability,long life and excellent electrical performance characteristics over the frequency range of DC-900 MHz
The REW-14 Coaxial Relays intended for switching the radio-frequency coaxial 50 ohm chains in without current mode to switchings.Perfect for switching the output of PA, connection of any HF-VHF-UHF antenn. Low circuit losses and stable contact resistance, allowing for low thermal and RF noise generation.
Perfect and easy for converting your HF-UHF amplifier to QSK !
