...and then hook the short coax to the port you want to setup on and then hook the meter to the other end of the short coax and the original coax that goes to the receiver. Another words the analogue meter is hooked up in series between the receiver and the LNB. Works great! Later, DC
Obviously you have never done this. The 1000.x LNB's won't work this way. These multiple LNB's operate in a dual output mode depending on what you connect to them: Echostar refers to this as Default mode when the receiver is connected directly to the LNB assembly OR, DPP44 mode whenm the assembly is connected to a DPP44 ( or a digital tuning meter) first. IF you connect the LNB assembly to a
digital tuning meter or you connect the LNB assembly to a DPP44 switch it operates as you described, each of the three left ports output individual LNB signals. The 4th LNB Input port is disabled. However, if you connect the LNB assembly to a receiver
into port one first followed by optional receivers for ports 2, and 3, the LNB assembly outputs all three signals from the 3 LNB's to
all three ports simultaneously with or without the analog meter in the line.
So, if all you have is an analog meter and your receiver, you will need to do what I did here and connect your meter to PORT 1 as that is required to get power input with power side of the meter connected to your receiver. Then use some aluminum foil to block sat signals to the two LNB's you don't want to receive. This allows the free unfoiled LNB to output it's intended signal to the port #1. Normally you'd want to do your first azimuth and elevation with the analog meter to the center LNB first so you'd put foil over the two outer LNB's for this first adjustment. Which one you do next is optional but I would recommend the one furthermost from the center as this one will more greatly affect your skew adjustment. Zero in the skew and then move the foil so you block that outside LNB now plus the LNB in the center and do the remaining course adjustment to the one nearest the center. Should be a minor skew adjustment by this time.
Your receiver should be showing good signal on all LNB's now on the receiver's Menu 611.
In my case I found that the 61.5 LNB on a couple weak TP's was just too low for rain fade issues so I set up another larger dish for that satellite and disabled that LNB on the main dish.
I used the analog meter to do the rough and then used the receiver outputting to my sling box and using sling player on my smart phone on the roof to do the final check. If using a receiver Menu 6,1,1 to do the checking you can remove the foil from the LNB's because the receiver Menu 611 screen can isolate the LNB's , TP's and signals but this method is much slower and more accurate than the analog meter.
