P1D-1V Vacuum Military Antenna SPDT relay.
These relays were used in the military equipment of the USSR. Vacuum Antenna Relays intended for switching the radio-frequency chains in without current mode to switchings. Perfect for switching the output of PA, connection of any HF antennas. Low circuit losses and stable contact resistance, allowing for low thermal and RF noise generation. Many Ham’s use these relays for switching the input or output power amplifier up to 1kWt on up to 76 MHz in without current mode to switchings.
A special series of relays for use in tropical conditions of high temperature and humidity.
