Outer Limits 4x4 Board

Anyone have any experience with or opinion on these stick-on UHF aerials. Thinking of putting one on my back (vertical) window.

In the RF wold that would not meet australian standards. The radiation pattern would be crap, atleast half your tx power would be in the cab and radtiated through your head.

You would be no better off than using a portable in the cab.
