This 60 Series is a patented, high isolation option (“G” option) for transmit-receive applications. This option leaves the unused input open, and increases the isolation on the N/C connector to 85 dB at frequencies up to 500 MHz. This option reduces the maximum power rating of the N/C connector to 20 Watts, and will increase the VSWR of this terminal above approximately 400 MHz.
Designed for operation to a maximum power level of 1 kilowatt.
Coil Voltage: 115vac
