I have a DST3000 & second Directv receiver that I would like to connect to my 65H80. I would rather not run another cable from my dish to hook up the second receiver.


I have been using an A/B switch but it is kind of a pain.


Can I use a diplexor to hook both receivers to my TV..I will

only be using one receiver at a time.


Any input before I give this a try?


Thanx Pete

At a minimum you need 2 coax cables from the dish, one to each receiver, or to a central distribution switch for several receivers.


You also need a dual feed LNB.


To get twice the bandwidth, right hand and left hand circular polarization is used, where half the channels are on one and half the channels are on the other. If you are watching a channel on the left hand polarization, and the other tuner is on a station requiring right hand polarization, you have to have an LNB with 2 outputs, and thus 2 feed lines. A "splitter" will only work if both receivers are on the same polarization, and then will require a DC path from one receiver with the other DC path blocked to protect from one receiver feeding DC to the other.
