 Two stage variable FM trap attenuates stations in the FM band (88 to 108 MHz). When both stages are tuned to a single frequency, it will be attenuated 26 dB or about 1/20 of its previous level. When each stage is tuned to a different frequency, it will be reduced from 7 to 10 dB or 1/2 to 1/3 of the original level.
Used to reduce strong signals from local FM stations and prevent overload of amplifier and TV sets. Unit is enclosed in weatherproof housing for mounting on antenna boom, mast or wall. Will pass power to antenna-mounted preamplifier. Mounting hardware, F-connectors included. (Tunable traps require the use of a scope, analyzer, or signal level meter to tune accurately.)
*Requires signal level meter or spectrum analyzers to tune. Professional installation recommended.

Trap may be tuned over the frequency range of 470 to 810 MHz. Features two separate traps. Both may be tuned to the same frequency to reduce it -15 dB, or separate frequencies to reduce 8.5 dB.
Can be mounted indoors or out. Passes VHF frequency; AC/DC passive. (Tunable traps require the use of a scope, analyzer, or signal level meter to tune accurately).
*Requires signal level meter or spectrum analyzers to tune. Professional installation recommended.
