TVRO Interference Filters
(Compatible With Digital LNB’s)

  • Eliminate Out-of-Band Interference at your C-Band Receive Antenna
  • Low Insertion loss
  • Low Group Delay Variation - Typically ≤ 8 ns (Ideal for Digital Applications)
  • Economical Price
  • Quick Delivery (Stock to 1 Week)
  • Less Than 6 inches Long (Fits Under Standard Weather Housing)
  • Available for all International bands
  • Also rejects transmit band (5.8 - 6.5 GHz) - eliminating the need for a separate transmit reject filter
The Model 7893D (7894D) C-band bandpass filter is installed between the feedhorn and the LNB (or LNA) to suppress strong out-of-band interference caused by marine or airport radar systems. Coastal and marine navigational radar frequencies (2.9-3.65) GHz just below the C-band, frequently wipe-out transponders (1-5) on satellite dishes installed near harbors. While airport altimeter signals (4.25-4.40) GHz tend to affect transponders (22-24) at receive sites located near airports.

The 7894D GUARANTEES IMPROVED RETURN LOSS (17dB min), WHICH WILL PROVIDE ADDITIONAL SIGNAL TO THE RECEIVER
