   en.wikipedia.org/wiki/Cellular_repeater

   A cellular repeater (also known as cell phone signal booster or cell phone signal amplifier) is a type of bi-directional amplifier used to improve cell phone reception. [citation needed] A cellular repeater system commonly consists of a donor antenna that receives and transmits signal from nearby cell towers, coaxial cables, a signal amplifier, and an indoor rebroadcast antenna.

3. Tower Mounted Amplifier - Wikipedia

   en.wikipedia.org/wiki/Tower_Mounted_Amplifier

   A Tower Mounted Amplifier (TMA), or Mast Head Amplifier (MHA), is a low-noise amplifier (LNA) mounted as close as practical to the antenna in mobile masts or base transceiver stations. A TMA reduces the base transceiver station noise figure (NF) and therefore improves its overall sensitivity ; in other words the mobile mast is able to receive ...

5. 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 ...

6. Repeater - Wikipedia

   en.wikipedia.org/wiki/Repeater

   Cellular repeater: This is a radio repeater for boosting cell phone reception in a limited area. The device functions like a small cellular base station, with a directional antenna to receive the signal from the nearest cell tower, an amplifier, and a local antenna to rebroadcast the signal to nearby cell phones. It is often used in downtown ...

7. Low-noise amplifier - Wikipedia

   en.wikipedia.org/wiki/Low-noise_amplifier

   Antennas are a common source of weak signals. [1] An outdoor antenna is often connected to its receiver by a transmission line called a feed line.Losses in the feed line lower the received signal-to-noise ratio: a feed line loss of 3 dB degrades the receiver signal-to-noise ratio (SNR) by 3 dB.
