Hi,
I have a Gap Challenger, and the report on the antenna below would apply
with the exception of the frequencies mentioned... The Challenger does
best on 40 and 20 in my case. I have a more in depth review of it at:
http://nk7z.net/category/info/reviews/antenna-reviews/
It is the third review down from the top...
