Yes, I used a sloper on 10. Mine was a dipole, fed direcly with RG-213
(RG-8) coax, no balun, no tuner. I had the shield on the lower side and
the coax center on the upper side. It worked very well.

I have used thet very same setup you want to build and it works well.
It seems to have some directivity, (as it should) and a fairly low
angle of radiation. The one I built worked every bit as well as the
Shakespeare Super Big Stick that I was using on 29.100. If nothing
else, its cheap and almost invisible with nearly zero wind load.
My setup had no balun, just a coaxial choke of 5-6 turns about 8"
diameter at the feed. That choke was not given any thought or
engineering, I just thought it sounded like a good idea. Please, no e-
mails telling me that the choke would never work like that. ;-) I fed
the thing with RG-8X and put about 450 watts into it with no trouble.
