The Passive VGA Balun MB-VGAB that allows a VGA Signal to be

Transmitted via a single Cat5/5e /6 Cable . Used in pairs , the VGA

Balun allows VGA video to be transmitted up to 350ft (107m) via

Cat5e/6 at 800 x 600 Resolution . it is built in surge suppressor

to protect VGA equipment against damaging voltage spikes . The

VGA Balun works in conjunction with PCs , laptops,plasma, LCD

monitors and DLP projectors.

Applications

Boardroom systems, classroom projection systems
digital signage, custom residential AV, DVR monitor
extension, medical display systems
