Does the RF Extender work with the Scientific Atlanta Cable box?
Yes, it does. In order for the RF Extender to work with the SA cable box the receiver needs to be on the A setting. Most all other devices work off of the B setting. If you are trying to control the SA box and other devices, you would need to purchase an additional receiver. If you already have it on the A setting and it does not seem to be working properly, ask your cable company to force a system upgrade.
