Yes they say you can peak with the SWM LNB's with a SSB. I will tell you this and most other installers will tell you the same. The SWM LNB's suck to peak with. Get yourself an SL5 or 3 depending on what is used in your area, and use that to install with. I have one SL5 that I got off of an old dish that is the same LNB I use to peak every system. Main reason is that Directv LNB's seem to have a very wide range of how they read on a meter. So using the same one every time let's me know I am hitting what I expect.
