testing:
however -- test wise it isn't bad i got it tuned up on 40 meters at about 8 feet off the ground and it has an swr 1:2 to 1:5 from 7.30 to 7.175 mhz (without a transmatch). also does ok on 15 meter - tune up wise. bad news the performance is not great - signal pick up is several s units below my dipole, but it does work. from what i have read the antenna has problems in that most of the performance is based on feedline radiation (see the links below):
