I recently obtained a Hopper 3 to replace a well used Hopper 2. The installer used a DPH hybrid LNBF that receives only 61.5 and 72.7. I would like to also receive the 77 sat. He advised that I must use the DPH LNBF's and they do not make one that receives the 77 sat. However it looks like if I use the DPH42 switch, I can use my old 1000.2 eastern arc LNBF that receives all three of these sats. All the DPH42 installation diagrams show the use of a power inserter. Found the DPH42 on SolidSignal.com, but when I called they advised that it does not come with a power inserter and that the DPH42 is directly powered by the Hopper 3. I then checked with DishDepot and they advised that their DPH42 does need the power inserter and theirs comes with it. Which is correct????? is a power inserter required to use the DPH42?
