I have been hired to work on a music tour which will have a full 5mm LED video wall up stage and decorative LED flooring around the perimeter of the half court size stage. I was able to pre approve the manufacturers of the LED panels which makes all the difference in the world.
Both of these LED screens have very low RF emissions in the UHF bandThe US wall is from VER equipment rentals and is the Revolution Display 5mm product and has been tested to comply with FCC emissions, for what that's worth. The report is in the file folder.
The floor panel is manufactured by Tait and since it is only used by them and not sold does not need any FCC type approval it seems.
In the spectrum scans,
RED is the power off level,
GREEN is the spectrum directly at the front of the center of a 10' x 10' screen within 5" and
BLUE is the same but in the back of the panel. Clearly more emissions out the back
The first Picture is the VER 5mm and the second, the Tait floor.
