I agree with Dave's loss numbers for 44 ft element length.   

However, before giving up and using a shortened 44 ft. dipole, you may want to 
see if there's a way get the elements lengthened close to a halfwave and still 
keep spacing at 0.1 wavelength.   Perhaps bring the ends down if you're 
maxed-out on horizontal space.  If you can, then you can use my prior message 
as a guide for system loss.  I would still model it with the hanging ends.  
Otherwise, the 44 ft length on 40m is going to be a real looser with the 8KJ as 
the added element really drives the impedance down from mutual coupling and the 
short element length makes it too reactive to keep losses low, even when trying 
to match at the feedpoint.
