exactly, but even with using the TW1 and the tuner in the radio, if you note
where your antenna is normally, 2.5:1 on 40, 3.1:1 on 75, and what not, if
you suspect a problem sometime, that will change so it's not completely
useless you just need to know where it normally is on each band so you can
tell if something changes.
