Wes - Excellent points. One of the locals has very fine antennas, but really appreciates the fact that his PW-1 can make the SWR look a 'bit' better. At my QTH, and TUNER, is absolutely necessary... but that is because I have only one antenna, and it is usable without a tuner on only one band. The internal tuners in most rigs can't handle it... the tuner in my K3, or my KAT500, are perfect on most bands. But a 30' vertical is a HUGE challenge for ANY tuner on 160... and many can't handle it on 80.
