I have a 311 receiver that rusted out the coax for the satellite feed right at the connection port of the reciever. I have the receiver hooked up to a DPP 500. This has happend twice in about 6 months. Anyone have any ideas of what might cause this?

i would guess that there is an unsealed drip loop or a grounding block outside and water is migrating down the wire and into the house. since there is a voltage, water and 2 different metals you are getting corrosion.
Yep water is wicking into the house from the outside. need to go over all connections and cables to find the source. BTW you need to replace the cable from dish to receiver now.
Check the seals where the wire enters the house. All you need is a little silicone around the entry point. Drip loops, like mentioned above are a good idea too.
My guess would be if I'm using the correct term is ( Electrolysis), I had the same problem with two 311's. The first time I noticed this I thought someone had put a piece of cork in the rf connection on the of the receiver, what it was is the copper wire had like melted to a flat wafer. I unplugged the receiver than with a small pointed tool took the copper out,cut the wire back about an inch and put a new fitting on,this happened about every six months until I had a service call and he finally grounded the antenna wire. I think the two metals reacted and or moisture plus current.
It's been almost two years now and no problem. I hope!!
