Term Explanation
Duplexer is a device that allows bi-directional communication. Its role is to isolate the TX signal from
the RX signal to ensure that the transmitter and receiver can work normally. It consists of two groups of
band-stop filters with different frequencies, to prevent it from transmitting the signals to the receiver.
Feed Line is the cable or transmission line that connects the antenna with the radio transmitter or
receiver.
Voltage Standing Wave Ratio (VSWR) is a value that measures how well a load is
impedance-matched to a source.
Squelch is a circuit function that acts to suppress the audio output of a receiver in the absence of a
sufficiently strong desired input signal.
