  2. Outdoor wood-fired boiler - Wikipedia

    en.wikipedia.org/wiki/Outdoor_wood-fired_boiler

    The outdoor wood boiler is a variant on the indoor wood, oil or gas boiler. An outdoor wood boiler or outdoor wood stove is a unit about 4-6 feet wide and around 10 feet long. It is made up of four main parts- the firebox, which can be either round or square, the water jacket, the heat exchanger, and the weather proof housing. The fire box ...

  3. Diplexer - Wikipedia

    en.wikipedia.org/wiki/Diplexer

    The diplexer is a different device than a passive combiner or splitter. The ports of a diplexer are frequency selective; the ports of a combiner are not. There is also a power "loss" difference - a combiner takes all the power delivered to the S port and equally divides it between the A and B ports. A diplexer does not.

  4. Duplexer - Wikipedia

    en.wikipedia.org/wiki/Duplexer

    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.

    Orthomode transducer, VSAT K u band Outdoor unit, includes feed horn, OMT, LNB and BUC Orthomode transducer (Portenseigne, France) Orthomode transducer, vertical and horizontal polarity Antenna side of OMT. An orthomode transducer (OMT) is a waveguide component that is commonly referred to as a polarisation duplexer.

  6. Wood-burning stove - Wikipedia

    en.wikipedia.org/wiki/Wood-burning_stove

    Wolfgang Schroeter invented the first wood-burning stove with a cast iron frame and glass door. This allowed the user to see the fire burning inside the stove. [16] A fireplace insert converts a wood-burning fireplace to a wood-burning stove. A fireplace insert is a self-contained unit that rests inside the existing fireplace and chimney.

  7. Talk:Diplexer - Wikipedia

    en.wikipedia.org/wiki/Talk:Diplexer

    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 ...

  8. Wood fuel - Wikipedia

    en.wikipedia.org/wiki/Wood_fuel

    Outdoor wood boilers also typically have short stack heights in comparison to other wood-burning appliances, contributing to ambient levels of particulates at ground level. An increasingly popular alternative is the wood gasification boiler, which burns wood at very high efficiencies (85-91%) and can be placed indoors or in an outbuilding.

  9. Radio repeater - Wikipedia

    en.wikipedia.org/wiki/Radio_repeater

    In same-band repeaters, isolation between transmitter and receiver can be created by using a single antenna and a device called a duplexer. The device is a tuned filter connected to the antenna. In this example, consider a type of device called a band-pass duplexer. It allows, or passes, a band, (or a narrow range,) of frequencies.
