I currently have a SL3 LNB. A tech was out today for an issue and he said I should have a reverse band LNB but he says I have too many tuners. I have 14 tuners and he said the max amount of tuners supported by the reverse band LNB is 13. He said he could put the reverse band LNB on but I would not be able to use all of my TV's at the same which really wouldn't be a problem. All 7 TV's are never being watched at the same time. So he installed this Reverse Band 3 Satellite LNB (3D2RBLNB). However once he had everything hooked back up it kept giving errors on all receivers that there was a problem with the satellite. He thinks it just that the LNB cannot handle that many tuners even if they aren't all being used. I'm not knowledgeable enough with DTV equipment to know if that is the truth or not. So my questions are does anyone have the Reverse Band 3 Satellite LNB using more than 13 tuners and if so....how? Also can the reverse band be used with the same dish that the SL3 LNB was using or does the dish need to be swapped out too? He ended up putting my SL3 LNB back to the way it was.
