The performance of the Decca Ant. is quite
intresting, the "gain"or at least the advantage over the normal
amateur installation appears to be at least 20db
(comparison with G4GVC at this location for
example). This is tremendous and
I dont see how it can be attributed to the
height alone,conventional wisdom says
that a short vertical has the same radiation
pattern as a full sise one,and even 300 feet is far short of full sise.So where
do we look for the explanation? It now seems even more important to do a
comparison with a "normal" ant.on site or near by.
I will be around at the weekend to do more
comparisons.Many thanks to the teams for giving us this unique opportunity. 73s
Laurie.
