Westell’s Band 14 / FirstNet Notch Filter helps to eliminate frequency interference with cellular sites and public safety applications that have Band 14 deployed.
Nearby AT&T sites can cause interference to wide band BDAs (bi-directional amplifiers), additionally a BDA may cause interference to a nearby AT&T site. These filters attenuate FirstNet’s band 14 by at least 30dB while passing the narrowband channels in the 700 and 800 bands.
