Hi Im currently developing a system that will
use two horizontally polarized recieving antennas
roof mounted on a car. What i want to do is have
one antenna recieving from the front and the other
receiving from the rear on the car. So i intend
to apply shielding to the rear sections of each
antenna to isolate the reception to front and rear.
I am recieving at UHF 868 mHz, does anyone have
any recommendations as to what shileding materials
to use? Many Thanks Matthew Webster

Hey dude,
I assume from the post you made
a little later, that you don't want your car to
look like it has a billboard on the roof! what I
would suggest (please note I am a bit new to the
RF game and more than a little daft) is to use a
mesh type screen between the two antennas, which
you should be able to get from your local hardware
store. however what may work better is a type of
repeater setup, where instead of using one antenna
for transmit and recieve, use two, but switch between
the two of them.
Hope that helps!
