Can you use a directv dish with a dishnetwork receiver?

Just to clarify on the answers given. The LNBs are different for DISH Network and DTV along with the receivers. The LNB and receiver takes the signal from the satellite and gives you your signal on your TV. As stated, you can't use different receivers and LNB from different companies. The dish outside does not matter, just the LNB and receiver.

Simply, no. The satellite dishes use different switching schemes internally for accessing the satellite transponders.

Bull....loney. I'm using an old 18" DirecTV dish to receive signals from a Dishnetworks satellite at 119W. The satellite receivers will be different because different signalling protocols are used.
