I have on order a tilting system for my antenna to probe the
polarisation of incoming signals
for maximum audio clarity and gain.
There are instruments out there that can automatically tell you the
polarisation
without one taking the trouble to pan the antenna in different
directions.
Anybody out there follow such a procedure with the antenna or use a
homebrew
or commercial instrument to save time?

How do you change the polarity of a helical antenna?

You wind the Helix in the OPPOSITE Direction....... Duh.....
