On a CB radio, tune to Channel 1. Transmit from the radio or, on a CB radio, press the talk button. Observe and record the SWR reading.
What effect does a tuner have at the antenna?
The antenna tuner DOES increase the power transferred from the transmitter to the transmission line and therefore increases the power radiated from the antenna. The antenna tuner does not reduce the portion of signal lost in the transmission line. The antenna tuner DOES NOT improve the radiation efficiency of an antenna.
