When I upgraded to a Hopper3 and 2 Joeys the DPH 42 was not available in the U.S. I had the Tech install the EA antenna on a non pen-roof mount on the ground as a temporary install. I had 3 1m antennas already installed for my old hopper going into an SW44. I received the DPH42 and installed it using two of the 1m antennas peaked on 77 and 61.5 with DPP LNBFs and life was good. after about a month the DPH42 failed. I setup the old temp install EA 1000.2 and called Dish for tech to change out the failed switch. The Tech refused to change the DPH42 because they do not work in the US with DPP LNBFs. I told him that it does indeed work and showed him the diagram and he still argued his point. I asked him to at least peak in the 1000.2 EA antenna as I had only tossed on the ground aimed in the general direction. I went back into the house and noticed the Van leaving without any work on the signal. Wow, so much for Professionalism. To be fair I did let him know he didn't know what he was talking about and should get some more training.
