2. Integrated reception system - Wikipedia

   en.wikipedia.org/wiki/Integrated_reception_system

   An IRS mast (highest in picture) on a communal housing block, with a few of the aerials it will replace. An integrated reception system (IRS) provides broadcast signals from multiple sources (typically terrestrial television, FM radio, DAB digital radio and satellite TV) to multiple outlets, via a single aerial cluster and signal booster-distributor.

3. Antenna amplifier - Wikipedia

   en.wikipedia.org/wiki/Antenna_amplifier

   In electronics, an antenna amplifier (also: aerial amplifier or booster) is a device that amplifies an antenna signal, usually into an output with the same impedance as the input impedance. Typically 75 ohm for coaxial cable and 300 ohm for twin-lead cable. An antenna amplifier boosts a radio signal considerably for devices that receive radio ...

   That is, the antennas might both pick up the same station; the signal from the one with the shorter cable will reach the receiver slightly sooner, supplying the receiver with two pictures slightly offset. There may be phasing issues even with the same length of down-lead cable. Band-pass filters or signal traps may help to reduce this problem.

5. Signal strength in telecommunications - Wikipedia

   en.wikipedia.org/wiki/Signal_strength_in...

   In telecommunications, [1] particularly in radio frequency engineering, signal strength refers to the transmitter power output as received by a reference antenna at a distance from the transmitting antenna. High-powered transmissions, such as those used in broadcasting, are expressed in dB-millivolts per metre (dBmV/m).

6. Diplexer - Wikipedia

   en.wikipedia.org/wiki/Diplexer

   Typically, the signal on port L will occupy a single low frequency band and the signal on port H will occupy a higher frequency band. In that situation, the diplexer consists of a lowpass filter connecting ports L and S and high pass filter connecting ports H and S. Ideally, all the lowband signal power on port L is transferred to the S port ...

9. Antenna rotator - Wikipedia

   en.wikipedia.org/wiki/Antenna_rotator

   The Alliance Manufacturing Co. of Alliance, Ohio, and the Astatic Corporation of Conneaut, Ohio, manufactured popular radio and TV booster and rotary antenna systems. These products were heavily advertised for radio use in newspapers starting in the early 1940s, [ 1 ] and for use with commercial television sets from 1949 into the 1960s.
