Abstract

Implementations of the present disclosure relate to circuitry for automatically correcting wrong connection of an antenna to a radio frequency (RF) cable. The circuitry comprises a first single pole double throw (SPDT) switch and a second SPDT switch. The input pole of the first SPDT switch is connected to a first antenna connection line while the input pole of the second SPDT is connected to a second antenna connection line. The first antenna connection line is connected to one of a first RF cable and a second RF cable, while the second antenna connection line is connected to the other of the first RF cable and the second RF cable. The throw, to which the input pole of the first or second SPDT switch is connected, can be changed based on the RF cable to which the input pole is connected. Therefore, the RF cable can be connected to the corrected output to correct the wrong connection automatically regardless of the antenna to which the RF cable is connected.
