GB-4000, SR-4 & M.O.P.A.

Quick Start Videos


Important Information: In this Quick Start Video the GB-4000 is shown on the right side of the M.O.P.A. This was only done to make the video. When set up for personal use the GB-4000 should be located below the M.O.P.A. as shown in the photo below, on the left. If this is not done RF interference from the M.O.P.A. may damage the GB-4000 and its power supplies. In the photo below, on the right, is shown a close up photo of how the power supply wires should be wrapped up in tight rolls. If this is not done the loose wires may absorb RF energy that will damage the power supplies. We have found that a rolling cart, as shown in the photo below, works the best.
