It is provided with either of the following: 1.0MHz+1.0MHz between 450 MHz and 512MHz and band Window to Window Guard that’s more than 2.0MHz or 2.0MHz+2.0MHz in 450MHz to 470MHz band larger than 3.0MHz Window to Window Guard or 2MHz passband ranging from 450MHz and 470MHz as well as 1.0MHz passband between 470MHz and 512MHz.

The UHF public safety BDA also supports traditional analog and digital P25 P1/P2 communications concurrently. Also supported include ALC (Auto Level Control) channelizing and internal duplexing and simplex. Include narrow 32 maximum band filters and shutdown PA uplink to help in lowering noise for the base station. Uplink squelch channelizing also supported and comes with BDA oscillation prevention, courtesy of inbuilt set isolation tests. Intelligent configuration guaranteed by web based GUI and support for SNMP.

Compliances: NFPA 1221/IFC (dry contact alarms) and NFPA 1221/IFC (NEMA 4 enclosure).
