What would be the magic of using the Kaz Delta form where you have the hold up the center with a catenary rope between the two trees?
Wouldn't it make more sense to use the "SuperLoop" (Bruce Conti's term) which is like the Ewe with a bottom wire added? This is also similar to the Flag antenna which has the same rectangular shape but is fed halfway up one vertical side and terminated halfway up the other side. SuperLoop, like the Ewe, has feed and termination connections at the bottoms of the vertical wires.

That antenna requires two supports at the end, which you have. You could also consider the Double Half Delta Loop, an antenna with somewhat better directivity but with lower gain.

Thanks for the good article on the KAZ/DKAZ, Super KAZ. Now with the missing tree, I will have to figure something else out. I do have options, as the property is still there. Putting up poles is not really a good option as keeping them up without a lot of extra support and unless a person has gone through 90-100 MPH winds, they have no clue what things are like here. When roofs blow off, keeping up a pole 30 feet high has its' difficulties. But the prospect of a cord across from the two existing trees and using the center as the apex, may be an option, or there is another angle I can install a KAZ I think. It will take a bit of thought now.
