First poster - I did search the forums. I have a rule of thumb that if I don't find the answer in a couple of hours, then I ask, not just blind posting
By the way, the Google search function here is pretty worthless; I find the search apparatus that points to other posts as you key in your subject line here seems the only way of truly searching.
Second poster - Thanks, I couldn't quite get my magnifying glass and flashlight behind my 722 and every time I remove it means another cable falls apart LOL, typically one that I have to order. You did prove it is time to head to the eye doctor again ;-) Also I appreciate this link but as expected I have more questions. This link has now made me aware that I don't know the difference in a "Dish Pro" and one that is not.
I know that many years ago when I was more involved in this, there were 2 types of LNB apparatusi, one line (the newer line) that had an internal mixer splitter with a single block of cable outlets, 1-4 depending on the model and one (an older line) with what looked like two seperate but phusically attached heads that required that some mixer device be attached to combine the two side by side LNBs to 1 cable to go inside the home (supporting 1 receiver). Now I apologize for not remembering the names of all these devices as they say the memory is the second thing to go. I just went out to the garage just now after reading the PDF you pointed me to and dug out my 2 receiver "single piece" LNB antenna (with two coax connectors to support 2 receivers) but no where on it did I see the words "Dish PRO" (has number BSID10P20M that may also be wrong as my magnifying glass is not powerful enough).
I am still not certain even with the kind link and help if what I have is the "Dish PRO" and if this "separator" works with what I have or not. The garage antenna stored away as a spare doesn't have the words "Dish PRO" on the LNB housing and when looking up at the antenna on my roof (also a "1-piece with 4 coax outlets" on it) using binoculars, I don't see the words "Dish Pro" on it either.
I have tried many Google searches and the different antenna types I cannot find. ( "how to tell if you have a dish pro antenna" among others don't work
