does it only reflect rf? or is it conductive? i am studying on a
paint-on antenna system right now! heck, the perfect stealth antenna
is here! come on, there are SOME smart guys on this ng! lets get on
this project! hams are you interested? A CHEAP PAINT ON ANTENNA
SYSTEM! the ramifications are endless.

The paint is conductive if enough copper added to it. Chances are that
there will not be enough copper added for it to be conductive at zero
hertz but it does not have to in order to reflect short wave length RF.

For the conductive paint to make a spray on antenna it will need enough
copper in it to be conductive at DC. This is more practicable for an
antenna than spraying all surfaces of a room since that area is limited.
With enough copper in the paint on a good insulator you could make a
good antenna. You could use a small metal plate over the end of
the conductive painted area to transition through capacitive coupling
to coax to the radio.
