In th the process of making my tests on a dual
polaarisation antenna for my uhf repeater (one of
many).
I am persueing something that I should have done a
long time ago.I have had reasonable success with
opting for a site that needed 270deg coverage which
made what I have done within reason.
I have taken a standard commercial 4-stack-removed the
top dipole-replaced it with a 6dB collinear for the
vertical polarisation.
The remaining three folded dipoles I have place in the
horizontal pane at 0-90-180.(still experimenting with
the spacing)
The idea and theory is to reduce the deep nulls in
mobile and portable comms.
I would like to hear from anyone that has any comments
and experience in doing this-suely I can not be the
first to do so.
I have a keen interest in dual pol antenna arrays so
if you have any articles I would appreciate the
sitesand your comments.
