The chief advantage of a diplexer is that it allows two different devices to share a common communications channel.

For the diplexer to work, the existing cable must be able to pass the satellite frequencies with little loss.

Transmitters whose frequencies are too close together cannot be combined successfully by a diplexer.

An especially common case of this is where the diplexer is used to split the entire spectrum into low and high bands.

The diplexer must therefore have a stopband that is even wider than the passband.

The diplexer is a different device than a passive combiner or splitter.

In intercarrier system where the combining is achieved at a low level stage no diplexer is used.

A diplexer is a device used to combine two signals occupying different frequency bands into a single signal.

A diplexer is a passive device that implements frequency domain multiplexing.

In split sound system a high power diplexer is used at the output of the RF amplifiers.

The bias tee is a diplexer.

A diplexer does not.

The diplexer is useful in homes that are already wired with one cable, because it eliminates the need to install a second cable.

These usually have an antenna input and a diplexer, so that the antenna signal is also distributed along with the satellite.

The diplexer, being a passive device, is reciprocal: the device itself doesn't have a notion of input or output.

In this usage the high and low frequency signals are travelling in opposite directions at the shared port of the diplexer.

Stations at the same height on the same mast indicate the use of a diplexer into the same shared antenna.

A diplexer may be used as a form of duplexer, which is a device to enable bi-directional (duplex) communication over a single path.

If it is not possible to build a second antenna for the second transmitter due to space constraints, then the diplexer is used permanently.

A directional filter is a device that combines the functions of a directional coupler and a diplexer.

The ports of a diplexer are frequency selective; the ports of a combiner are not.

Each diplexer delivers a wide-band signal in a different band and it is essential that its signal does not contain out-of-band components, particularly harmonics.

At the output of the RF amplifiers both signals are combined by a high-power diplexer; the combined signal is transmitted.

A gas-discharge transmit-receive device (a diplexer) was developed for isolating the receiver from the direct transmitter pulse, thus allowing the use of a common transmitting-receiving structure.

In this application, there would be a diplexer on the roof that joins the satellite dish feed and the TV antenna together into a single coaxial cable.
