Highly Selective
7893D Series
The Series 7893D C-band bandpass filter is installed
between a TVRO feedhorn and the LNA or LNB 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) are just below the TVRO band and
frequently wipe-out transponders 1-5 in TVRO’s installed
near harbors. The airport altimeter band (4.25-4.40 GHz)
will affect channels 22-24 at TVRO sites near airports. The
model 7893D interference filter operates at RF before down
conversion. This prevents the generation of undesirable
mixer products and receiver “desensitization” due to strong
out-of-band signals.

TVRO Interference Filters - 13961 Series
For Multifeed Applications
13961 Series
The Series 13961 waveguide bandpass filter is specifically
designed for use in multifeed antenna applications. It virtually eliminates interference caused by navigational communications (radar) of commercial and military aircraft, as well
as coastal and marine vessels operation at frequencies
above and below the C-band. The unit is installed between
the LNA or LNB and the feedhorn. This lightweight, low
profile filter is ideal for multifeed applications which require
sid-by-side placement of filters (adequate radome clearance
is required). Since the unit does the filtering at the C-band
frequencies, LNA and LNB overload is prevented and overall picture quality is improved.
