The car key repeater (Keyless repeater) is a radio equipment, the main functional purpose of which is to read / receive a radio signal, amplify the radio frequencies of this signal and transmit the amplified signal further. In other words, this intermediate device relays or redistributes the received signal. Due to the fact that the repeater increases the signal strength, the signal travels long distances without loss of quality. The repeater is placed between two other network radio devices to receive a radio signal and transmit its amplified copy to a remote receiving point.
Using the repeater in illegal activities is prohibited!
