Back to the original question. This is probably a bad time to have a stranger running around your house. But there are two reasons why you should upgrade to a SWM system sometime. First, if you have any older SD only receivers, they will probably have to be replaced sometime in the next couple of years. They will have to be retired as DTV eliminates SD duplicates of HD channels. Most Ku Band SD only receivers depend on the guide data being on every Ku (101 and 119) transponder. Since before the introduction of SWM, the Ka band capable receivers get their guide data from one transponder (currently 101 TPN 27). That is what is on the SWM guide channel that feeds all receivers. Second, a SWM system is much simpler to connect and maintain, and it is what current installers are familiar with. I have had a SWM system since 2010, and only had to replace the LNB with a 21 tuner reverse band LNB to keep up with the latest technology.
