Of course that is what everyone would want to measure, but unless you
are working in the millimeter bands in a non-echoic chamber,
determining the true (absolute) radiation pattern can be quite
problematic.


We are looking at shortened, loaded verticals, monopoles. So you stick the
"standard" - quarter wave radiator in the test point, measure it at proper
point, then you replace it with "miracle" antenna and do the same, feeding them
with the same power. The difference is in overall efficiency. Lets not lose
sight of what are we talking about and what the real "problem" is.
How do you build igloo for 4 square? Comon guys, this is old stuff, has been
done for 100 years already. Lets not fly off on tangents.
Is anyone out there who "calorimetered" the antenna?
