I don't know much about these antennas but I have a friend in Colorado who
has one and we often talk on 20 or 40 meters. He has only 100 watts output
and he puts a strong signal into Alabama. It certainly seems to work for
him. I have a Carolina Windom and I believe his Isotron performs better
than my windom.

Due, no doubt, to radiation from his feedline. If you both
replaced the vertical section of your feedline with a good
ground-plane vertical, it might improve even more.
