INRAD Roofing Filter 4kHz/70.455MHz for FT1000MP, MARKV FT1000MP Series

The FT1000MP (MARK-V and FIELD inclusive) Roofing Filter help to reduce the third order IM products from multiple strong signals in the 2 to 20kHz region either side of the tuned frequency. IMD dynamic range will be improved 10dB or more for some signal spacing. Filter is assembled on PCB with High Dynamic Range Feedback Amplifier, which cover the Filter loss plus a dB or two.

This roofing filter substantially reduces the third order intermodulation from multiple strong signals in the 2 to 20 kHz region either side of the tuned frequency. It has much of the benefit of the IF Noise Reduction Mod and in addition it reduces the close in IMD. This is particularly important for stations with big antennas or stations which regularly receive loud signals.

This is a plug-in, no-solder mod that can be easily removed. The roofing filter also works in the Mark V and Mark V Field, except it requires soldering two connections.

Please see our document titled "A Few Words About Roofing Filters" for more details.

Note: This unit cannot be installed along with the Inrad FT-1000MP IF Noise Reduction Mod. Only one or the other can be used.
