Diplexers are devices that separate signals by frequency. They allow two different band radios to share an antenna, or a radio to use two different antennas.

A diplexer at the top combines the two antenna signals to the single coaxial feedline, and a second identical diplexer inside the building separates the feedline signals to the two dispatch radios. Some diplexers support as many as four antennas …

Double or triple the versatility of your multi-band antenna! Our duplexers and triplexers allow you to connect multiple radios to a single antenna, so you can use each radio to operate a different band. This eliminates the need for multiple antennas and extra coaxial cable.

Feb 21, 2012 · If you have an antenna, you can use a splitter to make that antenna serve more than one television. If you have a cable or satellite system, you might be able to use a splitter to add TV to another room.

Nov 28, 2016 · A Diplexer is a 3-port passive device that allows two different devices to share a common communication channel. It consists of two filters (Low Pass, High Pass or Band Pass) at different frequencies connected to a single antenna.

A diplexer is designed to separate or combine different frequency bands, while a duplexer enables simultaneous transmission and reception on the same antenna by isolating the transmit and receive paths.

Mar 3, 2022 · Diplexers are small, box-like metal devices with one input and two outputs. And yes, they look very much like taps and splitters. These devices actively combine two or more sources in such a way that only a small frequency range from each source is allowed to pass.

Feb 15, 2025 · Choosing Between a Diplexer and a Duplexer. Use a Diplexer if you need to separate/combine signals from different frequency bands. Use a Duplexer if you need to allow simultaneous transmission and reception on the same antenna.. Real-World Example. If you need to connect an LTE cellular signal (800 MHz) and a Wi-Fi signal (2.4 GHz) to the same antenna, you need a diplexer.

The diplexer allows two different signals to be sent or received over a common antenna by separating or combining the signals depending on their frequency. Among radio amateurs, the diplexer is often used to separate the signals of VHF and UHF so that a radio amateur can work on both bands with a single antenna.

Jan 29, 2002 · Sometimes with receiving Antennas, problems arise with interference from out of band frequencies. One of many possible solutions is an Antenna Diplexer. Here we make extensive use of our knowledge of both Low Pass Filters as well as High pass Filters to incorporate both types into one combined filter I call an Antenna Diplexer
