Default The Lazy H does not seem to exhibit any gain over a dipole in thereal world

If you feed at the center of the line connecting the two radiating
elements the phasing will be correct regardless of the velocity
factor, because the length from the center feed point on the
connecting line will be the same from that point to each radiating
element. With this configuration of feeding don't put a twist in the
connecting line--the two radiating elements MUST be fed IN PHASE! If
they're fed out of phase the array will look like an Adcock direction-
finding antenna, with a deep null in the radiation pattern in the
broadside direction.

Just my thoughts,

Another point to consider, Mark, is that the azimuth beam width is
narrower with the lazy-H than that of the dipole. So perhaps the
apparent lower signal level is in directions off the side of the
radiation pattern, where one would expect the signal level to be lower
than that of the dipole at the same angle.
