2. Power dividers and directional couplers - Wikipedia

   en.wikipedia.org/wiki/Power_dividers_and...

   A 10 dB 1.7–2.2 GHz directional coupler. From left to right: input, coupled, isolated (terminated with a load), and transmitted port. A 3 dB 2.0–4.2 GHz power divider/combiner. Power dividers (also power splitters and, when used in reverse, power combiners) and directional couplers are passive devices used mostly in the field of radio ...

3. SMATV - Wikipedia

   en.wikipedia.org/wiki/SMATV

   The system consists of a master antenna and a matching transformer to match the balanced antenna with unbalanced cable and amplifiers. [5] Most antennas have an impedance of around 300 Ω. To convert it to 75 Ω, a matching transformer (or balun) is used. For trunk line isolation, a resistive inductive device known as a splitter is used.

4. Low-noise block downconverter - Wikipedia

   en.wikipedia.org/wiki/Low-noise_block_downconverter

   The basic model has only 2 connections and presumably has a local oscillator of 10.41 GHz with an intermediate frequency of 290–2340 MHz from an input of 10.7–12.75 GHz. This LNB seems to be the same as Unitron's ASTRA Universal Wideband LNB. [16] Two cables minimum are needed to access all channels.

5. Wilkinson power divider - Wikipedia

   en.wikipedia.org/wiki/Wilkinson_power_divider

   No loss occurs when the signals at ports 2 and 3 are in phase and have equal magnitude. In case of noise input to ports 2 and 3, the noise level at port 1 does not increase, half of the noise power is dissipated in the resistor. By cascading, the input power might be divided to any -number of outputs.

6. Diplexer - Wikipedia

   That cable would then run from the roof into the house. At a convenient point, a second diplexer would split the two signals apart; one signal would go to the TV set and the other to the IRD of the DBS set-top box. These usually have an antenna input and a diplexer, so that the antenna signal is also distributed along with the satellite.

7. Multiswitch - Wikipedia

   en.wikipedia.org/wiki/Multiswitch

   3 input multiswitches are available, which combine a dual LNB with an input from a terrestrial antenna. 5 input multiswitches are also available, which combine the 4 input "standard" multiswitch with an input from a terrestrial antenna. 5x8 (5 by 8) Multiswitches, which have 4 satellite input, 1 terrestrial antenna input and 8 outputs
