Inline trap used to block channel 3 coming from a cable system or an off-air antenna where channel 3 is being used.

Notes: If used on a system where Ch. 2, 3 and 4 are present, this inline trap can affect the reception of Ch. 2 and 4.

If the level of Ch. 3 on the source being filtered is too high, this trap may not completely eliminate the desired signal.
