[Antennas] Slopers

Has anyone had any experience with  dipole slopers?  I've used one with 
good (I think) results from a mountain location in Colorado.  But  I 
didn't have any other antennas for comparison.  This was  a 20M  dipole 
with a tree being the support .  The high end was about 20 feet up, the 
angle was about 30-40 degrees, and the low end was about 5 feet off the 
ground. I sloped to the East.  I was able to have regular sked with an 
Iowa station in the mornings and worked Sweden . This during Mid July to 
Mid August.. Has anyone modeled a sloping dipole similar to this?  

Mke Burger at the University of Hawaii at Monoa's ham radio club, UHAM, 
has modeled verticals and dipoles, and has a lot of good comparison 
info, and insights, on the clubs web site,   
http://www.chem.hawaii.edu/uham/index.html.  He shows that a horizontal 
dipole up 3/8 wavelength is hard to beat.

Thanx for any comments,  Terry,  WA�ITP
