One thing I've learned over the years, when it comes to antennas, you might 
as well try it and experiment because what works for me may not work for 
you, what worked in one QTH didn't work in another, varying drastically from 
the instructions for an antenna may or may not have much effect and might 
even make it work better. You really should be able to do at least something 
with what you want to do. Even the manufacturer of my antenna told me as 
close to trailers and metal sheds as I have my vertical it would never work 
and I'd be wasting time trying it, not only does it work but I didn't even 
have to adjust it very far off the settings the last person  had it at and 
not at all on most bands and it works just fine. If you saw  how close it is 
to all kinds of metal, you'd never believe it works. It amazes me daily.
