The FM Notch filter is designed to trap out single FM broadcast station energy from cable, MATV, television, or minor FM translator receiver applications. Television interference is common within the 115 dBu zone.  This product is used to solve the localized blanketing interference that FM stations are required by the FCC to resolve within one year of beginning operation, or within one year of changing antennas (CFR 47, 73.318). Many common blanketing interference problems can be quickly solved with installation of this shielded filter.  This remains a popular filter with many satisfied users.
