So I got 4K equipment installed and after having the tech come back and second time I had him replace my SWM 16 switch and old LNB with a reverse band so that I would be ready for any future 4K content. So I'm assuming that he installed a SL3 LNB. Not ever sure if there is a 5 yet? So i receive the Houston local channels, I haven't noticed that I'm missing any channels. I guess in this area I don't need a SL5?
