Take a run back to the Shack, dump the interuptor you bought, pick up these: Parts #15-1140 and #15-1253, tie them back to back via 300 ohm leads, insert in your cable before any equipment and voila, loop broken. Not very pretty but effective, (save slight signal loss; cheap enuf to experiment with tho.)
