The VGA Extender allows users to extend video signals beyond the A/V rack. The VGA Extender Series can be used to extend an analog signal to cover distances up to 330 feet. Industry standard Category 5e (CAT-5e) cable is used for the extension. The VGA Extender LR sender unit connects to your source using the supplied cable. The receiver unit connects to your display - up to 330 feet away. One CAT-5 cable connects the sender and the receiver to each other, extending your video flawlessly. Note: This is a new VGA Extender that goes double the distance of the previous version, and also has a trim-pot for fine video adjustment.
