Comba Telecom released the CriticalPoint™ Public Safety UHF BDA solution at the APCO 2018 Annual Conference & Expo.

The CriticalPoint UHF BDA supports frequencies from 450 MHz to 512 MHz and supports internal one-window or dual-window filters for various passbands within the NEMA 4 enclosure to lower overall costs, reduce installation costs, and save space. Additionally, features of the 700/800 MHz public safety BDA include supporting up to 32 narrow band channels (Class A) or four wide-band channels (Class B), Channelized Automatic Level Control and channelized squelch (Class A) are also incorporated in the UHF BDA. 

A new exclusive feature has been released called NetProtect™.  NetProtect allows the BDA to automatically turn off the uplink Power Amplifier when there is no traffic activity so ‘no noise’ is transmitted back to the base station, helping to keep the public safety network clean. The NetProtect feature can be found on both the latest UHF BDA as well as Comba’s 700/800 MHz Class A BDA.       

Other CriticalPoint UHF BDA Features:

  • Available in Class A or Class B
  • Available in AC or DC powered
  • 36dBm / 30dBm DL/UL Power, 95dB Gain (Simplex)  
  • Supports SNMP v2 & v3 / Easy-to-use OMT web interface
  • NEMA 4 and NFPA 1221/IFC compliant as well as FCC and UL/IC approved
  • Built-in mandatory isolation test to prevent BDA oscillation
