I currently have a simple Directv SWM setup: A Genie HR34-700, and one HD receiver H25-500 in another room. In my coax junction box outside, the installer utilized a 4-way SWM splitter (MSPLIT4R1-02), leaving 2 unused outputs. Now I'm interested in adding two more HD receivers (probably H24 or H25 models) in two bedrooms that already have coax runs to the outdoor junction box. So all I would need to do is remove the 2 75-ohm terminations from the unused ports on the splitter, and attach the two coaxes. Then it is a simple matter of connecting the new receivers to the coax receptacles in the bedrooms. The new system will have 8 tuners (the max for my SWM LNB): 5 for the Genie, plus 3 for 3 HD receivers. So my question is, can I do this myself (self-install) or will I need to pay Directv for a service call? The Directv website is not clear on this. My preference is for them to just send me the boxes and let me do it myself. However I've read on these forums that DTV can be apprehensive on self-installs. If self-install is an option, will they "pre-activate" the boxes or will I need to call? If self-install is not an option, what would it cost for a tech to drive here and screw in 2 coax lines? My next question is about availability and pricing of the various receivers. The info on Directv's page is confusing or non-existent. I am also considering "Genie mini" which I understand does not contain a tuner but rather utilizes a tuner from the HR34. No price is given. If I select the "HD receiver" option, it shows H24 in the text but a picture of the H25. Not sure what they are currently shipping.
