FTA v. DN Receiver Power Output & Requirements.
FTA
Most FTA Receivers put out 13v for Vertical Polarization and 18v for Horizontal Polarization at 500mA Max
DN Receivers
These receivers put out 13v for Vertical Polarization and 18v for Horizontal Polarization at 750mA.
DishPro Plus v. DishPro LNB’s
DishProPlus LNB requires approximately 650mA to power up ONLY when using the third LNB input. In other words a three LNB Setup. What this means is that if you are running a DishProPlus LNB for FTA as long as you don’t use the third LNB input then your FTA Receiver will power this setup without a problem because it would work as a DishPro Twin/Quad LNB and only require approximately 400mA to power up which is easily supplied by your FTA Receiver.
When hooking up a DP34 Switch to a DishPro Twin LNB the power requirement jumps to 450mA which is still easily supplied by your current FTA Receiver. Where people run into problems is when hooking up a third LNB to the DP34 as the power requirement then goes up to 500mA which is the max output of a FTA Receiver.
Having said that, the purpose of running a DP34 switch is to be able to run multiple FTA Receivers on a Three LNB System which is why people seem to think they need a Power Insert. This, however, is a misconception because more than one FTA Receiver will be used and even if only two FTA Receivers are used they WILL provide more then enough power to run the setup.
Last but not least is the misconception of having to leave the receiver on! Not sure where this came from, but if you think about what I’m about to say for a little while, it will make sense. Why is it that we disconnect all receivers in a setup from the Wall Outlets when messing around with cables and switches? To avoid damaging your switches (you know the DISEcQ’s that everyone seems to be blowing). This is because even when turned off, the receiver, be it FTA or SUB, will continue to provide power to the LNB’s. Hence the reason you do not need to keep the receiver turned ON!
LNB Power Requirements & Polarization
DishPro Plus is an LNB used by Echostar systems. It is used on the Dish 500 and some of the Super Dish systems. It has 2 outputs, and 1 input, using stacked polarity technology, (Converts the H polarity to V, interlacing it with the existing V polarity signals) resulting in only V polarity allowing longer cable runs (over 200 feet) by using only 13 volt LNB power and uses either Circular polarization or Linear polarization. It can be used with DPP and DP series switches (loses DPP functions when used with a DP34 however), as well as the new Dishpro Plus Separators
