2 -- Decibel Products DB 4021-2 UHF BandPass Cavity's
You are bidding on a PAIR(2) DB Products 4021-2 450-512mhz commercial bandpass cavities. They can be tuned down into the ham band easily. They are 5" high power. 3/4wave cavity filters. Better than the smaller 6" cavities due to their taller size. Easily handle 100w. Made in 1979, and are in very good shape. Have been sitting in low humidity environment for years. Each bandpass cavity filter is provided with adjustable selectivity capability. This is accomplished by physically rotating the coupling loops within the cavity to positions corresponding to total cavity attenuations of 1/2 dB or2 dB. Setting the loops to a higher insertion loss increases the selectivity or sharpens the frequency response curve of the cavity. The total insertion loss of a single cavity will be approximately that of the calibrated decal. Perfect for tuning ... moreout adjacent channel site interference. Tuning instructions can be found here. repeater-builder.com/db/pdfs/db-band-pass-cavity-filter-installation-and-tuning-instructions.pdf

TX/RX (now Bird Technologies) UHF Bandpass Cavity, 851-866 MHz
You are bidding on a TX/RX brand(now Bird Technologies) Bandpass cavity. This bandpass cavity is designed for a frequency range of 851-866 MHz. This cavity is from a combiner system and as you can see in the picture one of the loops has 2"N" type connectors on it which eliminates the need for a"Tee" when used in combining to connect to the next cavity. This can be replaced by a standard loop and made into a regular bandpass cavity. This cavity recently came out of working service and is in excellent functional and cosmetic condition.

Two Way Radio UHF 4 Cavity RX Pre-Selector Icom FIP-PR-45-4C Bandpass Filter
UHF internally mounted 4-cavity Bandpass RX Pre-Selector removed from an Icom FR4000 Repeater. The preselector can improve the signal quality of your repeater. The preselector provides additional rejection(or filtering) of unwanted signals. Including transmitter signals from overloading the receiver, and internal intermodulation(usually caused when a receiver is being overwhelmed by at least one signal) Has(2) N Male connectors. Can be installed between receiver and duplexer or between receiver and antenna. When each of the 4 cavities is properly tuned to the desired operating frequency the pre-selector will pass that frequency while rejecting unwanted frequencies. This unit really helps improve receiver performance in heavily congested R.F. environments such as Mountain Top Repeater Sites. Frequency Range: 440-512 MHz For use with Icom Repeaters: ... moreCY-5000. CY-6000, IC-FR3000, IC-FR4000, IC-FR5000, IC-FR6000, IAS 100D. IAS 100W.

TELEWAVE UHF BANDPASS BAND PASS CAVITY FILTER TWPC-4510-2 PRESELECTOR Duplexer
Up for auction is a Telewave TWPC-4510-2 UHF Bandpass cavity filter. It is currently tuned to 457.000 MHz, Its is in excellent condition and appears like new. It can be tuned from 400-512 MHz. But unfortunately I do not have the equipment or capabilities to re tune it. List price for brand new is $1.353. Shipping is for the 48 contiguous USA only. Must have a good standing Ebay account with 5 or more feedback. I accept PayPal only and the item will be shipped only to a verified address. Here is some more info from the spec sheet. The Telewave TWPC-4510-1 and 4510-2 are 10” diameter, ¼-wavelength. High“Q” bandpass cavity filters with superior selectivity. Bandpass cavities reject all frequencies outside a narrow pass band. These cavities reduce transmitter sideband noise. And also protect receivers against desensitization. TWPC-4510 cavities ... morecover 400- 512 MHz. These cavities also feature calibrated adjustable coupling. And insertion loss can be easily set from 0.5 dB to 2 dB or more to improve selectivity. This allows cavity response to be optimized for any operating environment. At densely populated sites. The 4510-2 cavity filter provides greater selectivity with minimum insertion loss. Multiple cavities can also provide a wider passband when required. Mounting rails are provided for all multiple-cavity filters. Excellent frequency stability is achieved by the use of a specially machined compensator and Invar rod. The pass frequency is temperature stable from-30°C to +70°C. Telewave Ground Loop technology places the center conductor of each coupling loop at DC ground potential for lightning protection and noise reduction. Heavy duty materials are used throughout each cavity to insure high performance and long life. Cavity top plates are machined from ¼-inch aluminum. And are heliarc welded to the cavity body at the high current point for improved conductivity and strength. This allows Telewave cavities to handle up to 350 watts. Depending on insertion loss.
