At Hamvention I got an ALPHA.. this is a 17' all band antenna (80-10 I think)
Have tried on 80, and 40, not yet on 20-15-10 and found the SWR well within spec and the ability of the radio's auto-turner to zero out. (I think 2.5/1 was the highest I saw)
BUt it does not hear as well as my long wires I think.. Have yet to do "A/B" testing but that will be done in 2 weeks.. Loads nice though. Mine is tripod mounted.
