Can the EM-406A be installed vertically or will that affect satellite reception?
What about mounting in a jiffy box that is then attached to the middle of an aluminium road sign about 3’ x 3’ in size so the EM-406 is vertical and only about 1/2" from the aluminium sign?
I currently have several units installed horizontally in that position so the edge is about 1/2" from the sign and they work perfectly. I now want to redesign the circuit board and install the EM406 vertically.
