Telewave TPCP-1556 Six 5" VHF Cavity Pre-selector Assembly [or UHF]

Description

For less than each, this is
six
5 inch VHF bandpass cavities, with oversized
adjustable loops
that will allow pass-loss around 0.2 dB.  When connected in series, they provide a very sharp, low-loss filter that is ideal for receiver pre-selectors or transmitter broadband noise attenuation, since they can handle 350 watts.  As pass cavities, they can be reconfigured to be a 3 to 6 channel  transmitter combiner and can also operate with greater selectivity on the third-harmonic in the UHF band of 444 to 522 MHz.
I prefer to ship these tuned to the lowest frequency to protect the tuning rods.  They are easily re-tuned to your desired frequency.

Factory information.
The Telewave TPCP-1556 preselector is specially designed for use with master receive systems to insure rejection of external noise sources. These bandpass preselectors provide
optimum receiver desense protection when installed between a receiver multicoupler and the antenna. In addition, their high power capability allows these units to be used as sideband filters on the outputs of transmitters or transmitter combiners.  Bandpass preselectors reject all signals outside a selected pass window, and are often preferred at congested sites.  These bandpass filters consist of 6 series-connected cavities, and are available in a wide range of pass bandwidths. Each model features “sharp-skirt” selectivity
with minimum insertion loss. For optimum performance, these bandpass filters are custom tailored to meet individual requirements.  Multiple-window configurations can be provided when more than one pass band is required.   Heavy duty materials are used throughout these bandpass filters to insure top performance and long life, and RG214 Mil-Spec cable is used for interconnections.  Temperature stability is maintained from -30 to +70°C by the use of temperature compensators, and threaded invar rod. Tuners are silver plated and sliding contacts are made with beryllium copper fingerstock. All models are 19” rack-mountable, and come with N Female connectors.  All units are factory tuned to customer-supplied frequencies and no further adjustment should be necessary. Field re-tuning or adjustment of insertion loss can be accomplished quickly if needed.
