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 virtu-
ally eliminates interference caused by navigational commu-
nications (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 over-
all picture quality is improved.
