   8-Port TV Distribution Amplifier. For households with multiple TVs, the Antennas Direct 8-Port TV Distribution Amplifier can split a signal with no noticeable impact on signal quality.

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 ...

4. Intermediate-frequency amplifier - Wikipedia

   en.wikipedia.org/wiki/Intermediate-frequency...

   More modern IF amplifier and demodulator in integrated circuit form Intermediate-frequency (IF) amplifiers are amplifier stages used to raise signal levels in radio and television receivers, at frequencies intermediate to the higher radio-frequency (RF) signal from the antenna and the lower (baseband) audio or video frequency that the receiver ...

5. Gain (electronics) - Wikipedia

   en.wikipedia.org/wiki/Gain_(electronics)

   The term gain has a different meaning in antenna design; antenna gain is the ratio of radiation intensity from a directional antenna to / (mean radiation intensity from a lossless antenna). Graph of the input v i ( t ) {\displaystyle v_{i}(t)} (blue) and output voltage v o ( t ) {\displaystyle v_{o}(t)} (red) of an ideal linear amplifier with a ...

6. Low-noise block downconverter - Wikipedia

   en.wikipedia.org/wiki/Low-noise_block_downconverter

   The LNB is a combination of low-noise amplifier, frequency mixer, local oscillator and intermediate frequency (IF) amplifier. It serves as the RF front end of the satellite receiver, receiving the microwave signal from the satellite collected by the dish, amplifying it, and downconverting the block of frequencies to a lower block of ...

7. RF power amplifier - Wikipedia

   en.wikipedia.org/wiki/RF_power_amplifier

   A radio-frequency power amplifier (RF power amplifier) is a type of electronic amplifier that converts a low-power radio-frequency (RF) signal into a higher-power signal. [1] Typically, RF power amplifiers are used in the final stage of a radio transmitter , their output driving the antenna .

8. 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.

9. Antenna array - Wikipedia

   en.wikipedia.org/wiki/Antenna_array

   An antenna array (or array antenna) is a set of multiple connected antennas which work together as a single antenna, to transmit or receive radio waves. [ 1 ] : p.149 [ 2 ] The individual antennas (called elements ) are usually connected to a single receiver or transmitter by feedlines that feed the power to the elements in a specific phase ...
