Example Bandstop Graphs:
UHF ch. 62 and Pager Band
Graph 1: UHF Ch. 62 Bandstop
Model CR7-ch.62U-20
- Bandstop attenuates ch. 62 by 20 dB to prevent signal overload of preamplifier
- Low impact on ch.62 picture quality, and low loss on chs 60 snd 64 (Mkr 3 & 4)
- Passband (not shown): 5 to 900 MHz, loss: < 1 dB loss ± .5 dB ripple
