Many antennas have a matching network to couple the feed line to the antenna. A poor antenna feed line is not improved with the tuner only power transfer is maximized - this works for receive and transmit - using impedance matching is always useful for maximum power transfer. • David started at age 8 building Using or teaching about electronic devices - that was 65 years ago.
