My signal strength has been declining. E* sent a repair guy to take care of it. Currently I have 2 Dish 500's. 110/119 & 61.5. I'm in Ct. I asked Dish if they would upgrade me to EA. I only have 1 receiver, a 622. Dish refused to change me to EA and install 1 dish, but instead replaced the LMB's on both 500's, tightened the loos antennas, and fixed the grounding and rusted cable connectors. Seems like it would have been beneficial to change over to EA so there is only 1 antenna to maintain, all MPEG4 and more astatically pleasing, but no. Any existing customers ever get upgraded to EA?
