Even if you don't have a Reverse Band capable LNB, the tech. is required to install one with all 4K upgrades
But for now, look on the HR44 for the LNB data in "System Info & Test" ----> "Genie info." under the receiver settings.
If you already have a Reverse Band LNB, then you should see "Reverse Band" listed next to a "RB/INTL" catagory.
The RB is for future-proofing as DIRECTV eventually plans to move all 4K programming there.
Ill take a look in a sec....actually on phone with DTV inquiring about 4K....she is telling me she can simply swap out C41 with a C61K without changing genies....IE HS17 or HR54.....and Ill get 4K.....wrong right??
