Antenna amplifier

Antenna amplifier for broadcasting service (here: TV broadcasting and FM sound broadcasting).

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 waves.[1] Many devices have an RF amplifier stage in their circuitry, that amplifies the antenna signal, these include, but are not limited to; radios, televisions, mobile phones and Wi-Fi and Bluetooth devices.
