OVERLAPPING FOOTPRINTS
When there are multiple radiators in a room, the footprints of the different radiators can overlap. If these
radiators are connected to the transmitter with cables having different lengths then the signal will reach the
radiators at a different time. This mismatch will results in the reduction or canceling of the infrared signal (in
places where the IR signal of the radiatiors have equal strength), thus creating black spots. For more
