So if understand you correctly (might be missing something), you have an SW-21 with a single tuner, and you buy a dual tuner. Instead of upgrading ($$$!) to an SW-44, you can put that Separator on the back, and it will work as well as an SW-44?
Isn't it working pretty much like a splitter?
Without a power insertor, how is the signal in terms of HD quality?
How much do these normally cost?
I've had customers with this type of issue, and we always tell them they need to run the second line and the SW-44.
If you have an SW21, you also MUST have Legacy LNBF's.
You CANNOT add a DPP Separator to any kind of Legacy setup.
To use the DPP Separator, you need to have a DPP Twin LNBF (either or both of the Outputs can feed a DPP Separator to feed Dual Tuner Receivers), or 2 x DP Twin LNBF's feeding a DPP33 or DPP44, an output of a DPP switch can use a separator.
what i would highly recommend is using a DPP. with the DPP, you will nee 1 wire going to each reciever but the great thing about it is that if you have HD PVR's, you will only need 1 line instead of 2 using a DPP seperator for Sat in1 and 2. With a splitter, it is impossible to devide your signal in two different lines. if you do so, you will be missing either all the Odd or Even transponders. so you will be missing channels. ane LNB sends out 13v for odd transponders, and 18v for even transponders. by putting a splitter on the line, the 18v from the LNB stops passing through so you will be missing channels. you will have no choice to have independant lines for each reciever you install.
