These are effectively a higher-performance version of a diplexer, typically with a narrow split between the two frequencies in question (typically around 2%-5% for a commercial two-way radio system). With a duplexer the high- and low-frequency signals are traveling in opposite directions at the shared port of the duplexer.
A diplexer is to allow two signals to be carried over a single path - i.e. to provide two-channel multiplexing. Generally a diplexer consists of a pair of filters with non-overlapping pass-bands, so it implements frequency-division multiplexing. I agree that a device can be both a diplexer and duplexer - if it is a diplexer where the two ...
A diplexer frequency multiplexes two ports onto one port, but more than two ports may be multiplexed. A three-port to one-port multiplexer is known as a triplexer, and a four-port to one-port multiplexer is a quadplexer or quadruplexer. A typical diplexer may have around 30 dB isolation between its L and H ports.
Isuzu Elf box truck. A box truck—also known as a box van, cube van, bob truck [1] or cube truck—is a chassis cab truck with an enclosed cuboid-shaped cargo area. [2] On most box trucks, the cabin is separate to the cargo area; however some box trucks have a door between the cabin and the cargo area, box trucks tend to be larger than cargo vans and smaller than tractor-trailers with movable ...

Great Dane, formerly known as Great Dane Trailers, is a Chicago, Illinois based manufacturer of truck dry van, refrigerated van and flatbed semi-trailers.Established in 1900 by J.P. Wheless and T.H. McMillan as the Savannah Blowpipe Company [1] in Savannah, Georgia, it has gone on to become one of the world's largest manufacturers of commercial truck trailers.
The main difference between them is the different structure. The frame dump trailer has a large beam that runs along the bottom of the trailer to support it. The frameless dump trailer has no frame under the trailer but has ribs that go around the body for support and the top rail of the trailer serves as a suspension bridge for support.
Mobile homes are often sited in land lease communities known as trailer parks (also 'trailer courts', 'mobile home parks', 'mobile home communities', 'manufactured home communities', 'factory-built home communities' etc.); these communities allow homeowners to rent space on which to place a home. In addition to providing space, the site often ...
