question about DPP44

[JLHare]

2 questions......

1. Ok so the 44 switch is great we can hook up dual tunners with one cable but why do you think dish will not pay for the 44 in an install. (I work for a retailer company and Boss say's Dish told him "beacuse of time saved" they will not pay for it in the install). I can understand eating the 5 dollar Separator but the switch??

2. I can find enough info about the Separator. Has any one tried to wire one in backwards like a diplexed system? Seems to me the Separator does the same thing anyway, just moves frequencies around.. Is the 44 even realy needed or is that just a way for Dish to make more money?

You'd get a better response in the Dish forum. I can't say anything about E* not paying for the switch; I'm not an installer. But the DPP44 and separator are indeed necessary for some installations, especially apartment installs where the tenant wants a dual-tuner receiver but the landlord won't let you drill a second hole in his wall. (I was in a similar situation, which is why I researched it; but my landlord approved the second hole before the DPP44 finally came out.)

Old "legacy" installs could only put either the odd or even transponders of one satellite on the cable at one time. DishPro gets around this by stacking both odd and even transponders on one cable; so only the satellite requires a switch. DishPro Plus takes DishPro in a different direction by making the two halves of the stack independent; say, one could be 110 odds, and the other 119 odds. But to do this, you need a switching device that can put two different birds into the cable; presently the only such device is the DPP44. (There will also be a DishPro Plus Twin LNBF, but AFAIK it's not yet available. It's the only LNBF with an *input*; it's designed to let you "daisy-chain" a Dish300 aimed at a wing bird, so you won't need ANY external switches for ordinary two-dish residential installs.)

A reversed separator shouldn't work because all technical indications are that the separator does NOT move frequencies around; it's merely a low/high-pass filter that sends the low band (900-1450 MHz) to output 1 for TV1 and the high band (1650-2150 MHz) to output 2 for TV2. In theory, a splitter could work as well; but because of how E* programmed DishPro Plus receivers, it won't work. You also can't use a separator with two individual receivers, because the receiver on output 2 won't be able to send DiSEqC signals back to the DPP44; a dual-tuner receiver can send all DiSEqC signals through output 1, as E* intended.
