[Antennas] antenna question

[W0DXZ@aol.com]

I never got a replay from my last post, so will try again
What happens, gain wise, to a signal if I use my 12/17M  3 el cushcraft beam 
on 15M?My rigs auto tuner  flattens the SWR,  
How would that sig compare  to if I just used a regular  3 el 15M beam. How 
much am I losing?  Is it worth getting a 3 3l 15 M beam, or should I just use 
the  3 el  12/17?
thanks
Bob W0DXZ
