Introduction
The duplexer is a critical part of many repeater systems. When searching the markets for a pre-owned unit, it is often difficult to determine the suitability of available units to a particular application. Finding specifications, especially for models that are no longer in production, can be a very frustrating process. This guide is intended as an aid to those searching for a duplexer or wishing to verify the performance of a unit that is already in service.
Basic specifications are given for each unit. This is not a complete technical reference. Station and mobile duplexers are included. This guide will be updated periodically as additional information becomes available.
CAUTION: many of the duplexers listed may require cable harness changes to operate in a specific "band split". Where information on band splits is known, it is reflected in this guide. It is important to verify that any unit has the proper length harness cables for the frequencies to which it will be tuned, as most duplexers will not meet their published specifications with the wrong cables or the wrong length cables.
Models that appear to be suitable for operation on amateur radio frequencies and at typical "ham split" frequency separation are identified in the list below by (HAM) after the model number. However, it is always advisable to check the unit's specifications for more information. Models marked (*) do not at first glance appear to be suitable for ham frequencies but have been used in the ham band (see note in specifications for details).
If you have information that would be useful to add to this page PLEASE send it to us!
