Dual Antenna Port
The standard Aprisa SR uses a one or two frequency ½ duplex transmission mode which eliminates the
need for a duplexer. However, a dual antenna port option is available for separate transmit and receive
antenna connection to support external duplexers or filters. The transmission remains half duplex.
Example of a 400 MHz dual antenna Aprisa SR:
4RF SRX, BR, 400-470 MHz, SSC, D Ant, 2E1S, EN, STD
Full Duplex Base Station
The Aprisa SR+ supports Full Duplex base / master station hardware. This option works with half duplex
repeater / remote radios. The base / master station can transmit while simultaneously receiving from the
repeater /remote radios. The ‘SR Compatible’ option must be enabled on the Aprisa SR+radio (see ‘SR+
Compatible’ on page 220).
Example of a 400 MHz full duplex Aprisa SR+:
4RF SR+, BR, 400-470 MHz, SSC, Full Duplex, 2E2S, EN, STD
