Another testimonial that HIGHER IS *NOT* ALWAYS BETTER :-)
Your observations probably say more about take-off angles
for the two antennas at 35 and 72 ft than the gain difference
between the two antennas. Note that over FLAT ground,
a 72 ft high 10M antenna will have lobes centered at 7 and 22
degrees with a NULL around 14 degrees. A 35 ft high 10M antenna
will have a broader lobe centered around 14 degrees, right where
the higher antenna has a DEEP NULL :-).
