Tom,

Never used one of these, but I think it is just half of a tuner.   It's 
got a tapped inductor with  a rotary switch  so you can add various 
amounts of inductance  and then tune the auto tuner into it.

You could monkey around with coax length to find something that suits 
your needed band, and maybe lose another band  at the same time.  Or a 
plain old external tuner to match whatever bands  the auto tuner doesn't 
like.


I'm not sure how much loss is involved with the MFJ thing,  but it's 
ease of use may make it an attractive option.
