Default The Lazy H does not seem to exhibit any gain over a dipole inthe real world

Just a quick update. I am seeing some gain with the Lazy H now that
the feed line exiting the antenna has been moved to a 90 degree angle,
but I don't think I am seeing the 5.9 dbd gain promised in the ARRL
Antenna Handbook. I would guess it is more around 3 or 4 dbd gain
with 1/2 wave length elements and 1/2 wave spacing between the top and
bottom elements. It seems like alot of trouble to go to when an
extended double zepp at the same height as top wire of the Lazy H
might do just as well if not better. The plus is the Lazy H may have
cleaner nulls off the sides which is helping with the occasional AM
carriers that are coming out of Central and South America.

Just curious, how are you measuring this -2 to -3 dB difference you are
referencing?
