What is the purpose of an antenna tuner?
Pick an answer to check it.
Answer: C. Increase power transfer from the transmitter to the feed line
An antenna tuner matches the transmitter to the feed line impedance, increasing power transfer from the transmitter into the feed line. It does not change the SWR on the feed line between the tuner and the antenna.
Tip: Tuner fixes the match, not the antenna.
