The dish that is on the roof of my house is still usable and the swm switch box is still good. The receivers were toast but directv sent me two new HD receivers. So I should be able to connect the swm switch box to the wall plate where the main tv is and connect the 2nd receiver to the wall plate in bedroom.
As far as the outside connection on the outside of my house the cable comes down from the dish and connects to a swm 4-way splitter. Can I connect a cable from one of the outlets on the splitter to the outside sat connection?
