I've used these off and on over the years. They are more suseptablde to
rf in the shack. At least in my experience. I had one up for 160 through
ten fried the ballon last summer with my alpha, but I could never get the
swr down on 160, no matter what I did. It worked fine on 75, but on 40,
same high swr problem. It was resonant at around 1700 kc and nothing I
did, shortening both ends didn't change much. It is worth a try and a
good compromise antenna for all bands.
