While its not perfect, you can compensate for the material part of the
offset by shortening or lengthening one of the feed lines by the difference
(figuring VF into the equation).

It's important to remember that this is all frequency-dependent, with its effect proportional to frequency, thus most sensitive on 10M.

Free space stacking gain of identical antennas symmetrically fed is 3 dB with lossless combining.
