But again...there is NO point whatsoever to be using any of the old triple sat dishes, when the new D500 dish/hybrid LNBF, is ALL you need, for ANY install now. And to repeat ad nausea, if a sub needs any type of service work on their system (upgrade receivers/replace defective dish/LNBF, move from EA to WA, etc.) they are going to replace the entire dish with the new D500 hybrid dish/LNBF - period!
