3. Preselector - Wikipedia

   en.wikipedia.org/wiki/Preselector

   A preselector is a name for an electronic device that connects between a radio antenna and a radio receiver. The preselector is a band-pass filter that blocks troublesome out-of-tune frequencies from passing through from the antenna into the radio receiver (or preamplifier) that otherwise would be directly connected to the antenna.

4. 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 ...

5. Loop antenna - Wikipedia

   en.wikipedia.org/wiki/Loop_antenna

   Small-loop receiving antennas are also almost always resonated using a parallel-plate capacitor, which makes their reception narrow-band, sensitive only to a very specific frequency. This allows the antenna, in conjunction with a (variable) tuning capacitor, to act as a tuned input stage to the receiver's front-end, in lieu of a preselector.

6. Indoor antenna - Wikipedia

   en.wikipedia.org/wiki/Indoor_antenna

   Being close to other electric or electronic equipment in the building, an indoor antenna is prone to picking up more electrical noise that may interfere with a clear (analog) reception. [2] Used for digital broadcast, the noise is less of a factor than analog broadcast, which recently makes this type of antenna a more popular solution.

7. Precoding - Wikipedia

   en.wikipedia.org/wiki/Precoding

   Precoding is a generalization of beamforming to support multi-stream (or multi-layer) transmission in multi-antenna wireless communications. In conventional single-stream beamforming, the same signal is emitted from each of the transmit antennas with appropriate weighting (phase and gain) such that the signal power is maximized at the receiver output.
