Indoor Channel Grouped Band-Pass Filters

Industry experts predict that 92% of homes in the UK will suffer from “overlap interference” after the Digital Switch-Over (DSO)

where signals are arriving from 2 or 3 competing transmitters and potentially causing reception problems. The solution (if you’re not

going to fit a new channel grouped aerial) is to fit a band-pass filter prior to the TV or set-top-box input.

 

 

High Out-of-Band rejection >-30dB typical

Low In-Band insertion loss <2dB typical

Reduces overlap interference from out-of-band transmitters

High quality fully screened die-cast metal housing with F connectors

Colour coded label for easy aerial group identification

Visible mounting holes & slots for easy fixing

 

Also available in this this range of Indoor Channel Grouped Band-Pass Filters
