"...Ditch the 43 foot vertical! The 43 foot vertical craze is a joke, as
you can see by the figures, Tom, W8JI, gives you in his post showing
feedline loss and SWR...."
With a 1:4 unun at the base of the antenna, the VSWR from 40-10 meters is
not bad - resulting in minimal coax losses. However, the VSWR on 80 and 160
meters with or without the unun is terrible, and you should match the
antenna at the base on those bands. See the "Articles" section at
www.ad5x.com for 160/80 meter matching ideas.
