It is a requirement to build telecommunications system in dual-frequency simplex mode and install filtering devices in its antenna sections in order to create favorable electromagnetic environment and improve reception conditions at sites with big number of control radio stations.
Usually mobile terminals with common transmit-receive antenna are employed as stationary radio stations. But to build previously mentioned system it is required to divide it into separate terminals, receiving and transmitting. Ferrite circulator will help with this. Possessing unidirectional conductivity it will easily provide your radio station with two TX and RX connectors with minimal insertion loss (0.4 dB).
