I seem to recall reading that the "ideal" angle between the legs was 110 degrees. How that was derived or even if it is true I do not know.

I had a half sloper and converted to an inverted vee. I had done fairly well with the half sloper and not too bad with the inverted vee but with the inverted vee I would occasionally see cluster comments that I was deaf from EU. Nothing scientific here. Plotting QSOs between the two showed that the more distant QSOs were on the half sloper but that could be propagation or other factors not specifically because of the antenna. The half sloper was attached to a 100 foot  45G at about 66 feet and the inverted vee apex was at 95 feet suspended out from the 45G. At the top of the 45G was a KT36XA, 80M rotatable dipole, and a 2 el 40M yagi. The two were not up at the same time so there is no true A/B comparison and RBN wasn't around yet.

In the states, we consider any wire in a "v" shape suspended upside down to be...wait for it... an inverted vee, regardless of height as far as I know.

Are you suggesting that in Merrie Olde England there is a specified angle between legs that define a "v"?

least 100ft high for it to be an inverted vee.
