About two years ago, I purchased a 4722 with Dish500, and a 7100 as a second receiver. At that time, I could have sworn that my Dish500 receiver had a dual LNB on it. The Dish500 drove two SW21s and all was simple.
About six months ago when Dish added additional locals for the San Francisco Bay Area on 148, I called them up and had a professional installer add on a 148 dish for me. Since I didn't do it myself, I'm not sure exactly what he might have changed. I thought he just added the other dish and cascaded the SW21s so that both receivers could get all three sats.
However, I was looking at my dish (from the ground), and it looks like my LNB might have changed from the one I installed. Is it possible that the installer changed my dual LNB to a twin? Would a twin even work with a 4922(software upgrade) and a 7100?
The reason I am asking this is that I am going to install another receiver (721). That will give me a total of four tuners plugged into 3 sats. I want all tuners to receive all sats. Unfortunately, if I've been switched from a dual to a twin, I'm not sure I can just plug everything into a SW64 anymore?
I've got plenty more questions, but I'd rather just start off with the simple question--from 30 feet away, how can I tell whether I have a twin or a dual? If a twin would not work with a 7100, then I must still have a dual (and my memory of what it looked like is just faulty...)?
Check switch on the 4922 shows SW21 3-SAT configuration.

Oh, hell, here are the other questions as well....
Question 2: If, indeed, I have a dual LNB on the 500 and a single legacy LNB on the other dish, I assume I should just rip out all the SW21s, plug all of the dishes into a single SW64, and all of the tuners into the output of the SW64, correct? Anything more complicated than that?
Question 3: Do I get any advantage in changing out the LNBs for DishPro LNBs and a SW34 setup? It looks like the only difference between legacy and Pro setups occurs between the switch and the LNBs themselves (and, of course, the software on the receiver). Remember, I've got a 4900 and a 7100, and now that my 7100 has stopped crashing constantly (yea!!!!) I am not all that interested in throwing it out the window.
In my 3 sat/4 tuner configuration, it seems like a 34 and a 64 are functionally equivalent??
Question 4: If the installer "upgraded" part or all of my setup to dishpro behind my back, am I screwed now?
