Hello Mark !
You are more then welcome, i honestly did forget about your earlier question, glad it was answered in the other topic.
I dont think there is much to add...
If we sum things up:
-In an L-shape..it certainly will work, performance is slighlty down compared to a vertical Cubical Quad (roughly 2..3 dB)
-In an L-shape... horizontal performance is silmilair to a dipole at that height.
-In that L-shape it DOES have hor and vert components.
-in that L-shape it will deliver more stress on the rotator
(a thrust bearing is adviced)
-there are situations where the horizontal delta loop is king.
especially when mast height is as high as the surroundings.
The Delta loop will be"above" it... where a yagi wont.
-The horizontal delta loop has a very small turning radius
-The Vertical (polarisation) delta loop has a large turning radius.
-A low placed horizontal delta loop has a slight take-off advantage, though it is questionable one can notice the difference...that possible advantage will become less when placed at a sufficient height.
To get an idea what the delta loop in an L-shape does :
(this is not the V-quad from maco, but a random 2el delta loop results wont be better with the V-Quad though).

Perhaps it is worth mentioning you cant really model the metioned V-Quad delta loop using the (free) Eznec version or free 4nec2 version. Mininec will do a better job,but with large diameter differences you will still need to have confirmation of the results. And there are manufacuters providing wrong info when it comes down to modeling the delta loop...but thats another story. Im saying this cause i know there are many delta loops out there which are not performing to theyre abilities.
If one is only interested in DX... it is a good option (horizontal).
If one is interested in working locals (vertical) the advice would be to use a cubical quad.
Overall, certainly not a bad antenna which could suit someone needs just fine !
Kind regards,
Henry
