PRODUCT DESCRIPTION
Digital Audio Broadcast and TV Band notch filters are used to reject strong DAB and VHF TV Band signals. A good Notch filter will reject these signals and have low insertion loss for signals outside the band.
DAB and TV signals can saturate a receiver very easily. If a receiver is saturated it will not be able to pick up signals in other bands for which it was designed. A DAB notch filter can prevent receiver saturation.
This is a 7th order DAB and TV band III Notch Filter with excellent rejection in the 170 MHz to 240 MHz band in a sturdy plastic enclosure. The filter works up to 3 GHz with minimal out-of-band insertion loss.
