Graph: BR7-LP LQ - Semi-Adjacent Lowpass
Graph: BR7-LP ch. 64/66 LQ frequency response
- Pass frequencies from DC to ch.64, and remove ch. 66 and above
- Stopband: > 50dB from 463.25 to 1000 MHz
- Insert new content starting at 463.25 MHz
- Passband loss: 1.5dB (except near Fc, see Mkr 1 & 2)
- Transition: approx. 8 MHz separates passband at Fc and stopband at F

Order Info: model BR7-LP ch.(Fc/Fs) LQ
Specify: Fc and Fs*
Example: BR7-LP ch.64/66 LQ, or BR7-LP 467.75/475.25 LQ
* Fc = Cut-off (channel or frequency). Fs = minimum one channel (or 8 MHz) above Fc.
