Hi, I have 2 separate H24 receivers that are showing their age and would like to replace them with 2 Genie H54 HD DVR's. Their location really prohibits using a Genie wireless on the second TV so I need 2 receivers. I have a SL5 LNB with 2 cables going to each H24 receiver to account for all 4 cables out of my LNB. I do not have 4K TV's. My question is can I do a straight swap of receivers, or do I need a new Dish/LNB? Also, can it be done by myself or does it need to be done by a professional installer? Do I need any special equipment (besides a new LNB if necessary) like splitters or such if I switch to the new Genies? Any help would be appreciated. Thanks!
