Sorry if this belongs in another section.
Small and high gain are probably exclusive.
I would settle for just directional.
I am working on a project that could do with a tight 2.4ghz beam. :)
Found these, 30,33dbi
So in theory how tight could a beam be made?
Is there another way to form the beam, say fire it down a tube?
Wave propergation is not my strong point.
Any help appreciated
