Hi guys, I'm a longtime D* customer, currently with 4 DirecTivos on a regular 2 LNB dish, and am looking into upgrading one to an HD receiver. I really don't want to deal with installers and all that crap, and it seems like the dish and switch are easily found on ebay. I've always installed my own dish, run my own lines, etc. So what I'm wondering is, how difficult is the installation of the dish? I watched the video from the SolidSignal site, and they use an electronic meter to help align the dish- is that really necessary? Thanks!
