Just to clarify what harshness has said, the DP LNBs and switches are bandstacked and do indeed go out to around 2GHz, whereas legacy equipment only went out to... Ah... From about 1GHz to about 1.5GHz. The "Plus" part uses exactly the same bandstacked technology and exactly the same frequencies as DishPro not-Plus, namely about 1GHz to about 2GHz, so no change there. If somewhathelpful's somewhat helpful tech was replacing a legacy installation with a DishPro or Pro-Plus installation, then everything he said about low-frequency barrels or damaged cable is true. If instead he just swapped out a DPP twin for a DPP 1000.2, then there is actually no change to the IF at all and the tech's frequency argument is a red herring.
