stupid question why wouldn't it be the 44 into the 34? and shouldn't dish network make public there installation dish/switch calculator?
because as many have mentioned, if you have the DPP44 before the DP34 and you unplugged the power inserter, you would lose signal to EVERYTHING... if you have the 34 first, then to the 44... and unplug the power inserter, you will lose signal to whatever receivers are hooked up to the 44... the 34 would still work
As for Dish making their installation stuff public... They probably dont think they need to. They don't sell their equipment outright anymore, any new systems are supposed to be put in by an "installer" that should know what their doing...
