Yes. But that gain is only on the single band for which it is designed. 
When I first moved to W6, I had one up for a while. It worked, but the 
feedline needed a choke to prevent common mode noise pickup on the 
feedline. I added one and the antenna got quieter. The choke was applied 
at the point of the transition from two-wire line matching section to 
coax. Once I had Al in the air, I took it down.
