65 of vertical run for the inverted L.  My question is how much would this
gain for DX contacts?

The radiation resistance would double from 4 to 8 ohms.
The counterpoise likely has more resistance than that,
so you might be looking at as much as 3 dB improvement.

Has anyone built an identical pair of K2AV counterpoises
and configured them as a low "dipole"?  Then the resistive
component of the dipole impedance is twice as much as
the resistive component of the counterpoise.  Right?
