Kramer's new R1300S2 - part of the Cobra range - performs impressively over quite a distance; when used in conjunction with the Cobra TS2 transmitter, 1920 x 1200 images (WUXGA) can be sent 1300 feet. This is the equivalent of 4 football pitches.

 

The receiver also has eq/skew adjustments to compensate for cable timing errors over long distances.
