TIPS FOR BETTER VIDEO

With TV sets, the antenna cable is the most likely entrance point for inter ference. Use a single piece of shielded coaxial cable between the computer and the TV's antenna terminals. Your local electronics store should be willing to m ake this cable up for you. If your set has a shielded antenna connector, use it . If it has only screw terminals, install a coax matching transformer. Eliminate all unshielded wiring in the antenna circuit, and eliminate the TV/computer switchbox. Then you'll have to switch from TV to computer by physically switching the cables, but if you have the right cable connectors, that's not so hard to do.

If you MUST retain the TV/computer switchbox, run a wire from the case of the switchbox to a good ground. In houses with three-prong electrical sockets, the screws on the outlet covers are usual ly very well grounded.

You can use antenna filters to reduce screen interference on TV sets. Radio Shack's 15-581 and 15-582 have been known to give good results. Because you want to remove any interference being sent into your set, connect one end of the filter as close to the TV's antenna terminals as possible. Connect your switchbox and/or computer to the other end of the filter.

Finally, if you have interference that you suspect is coming in over the power lines, try a line filter such as Radio Shack's 15-1111.
