- ORDERING
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.
