Sat. my HR20 went dead. Tech came out and found problem with underground wiring. He was going to replace when I asked him about SWM. Said it would be easier than replacement. So he put up a SWM antenna and ran SWM wiring to my HR24 and other HR20 and all was under my protection plan. Also, they ran the original undergrond wiring number of years back. The tech guy was very efficient! Sweet that it turned out OK. Noticed when I tured on computer, media share had a direct tv program pop up about sharing photos,etc. Have to check it out.
