PrimeStar LNB to LNBF Conversion

One of the main problems in using a PrimeStar LNB with modern receivers is that it has a Horz and Vert output ports with no internal LNBF switching.

  They can be converted to a LNBF  by connecting the H V cables to the input of a DirecTv Multiswitch. Some setups with more than 1 receiver should have a multiswitch already installed at the house.

Connect the  Horz wire  to the 17v/18v port and the Vert wire  to 13v/14V port on any Direct TV multiswitch. The 4 outputs will work like a LNBF and can drive 4 FTA receivers.

Use 10750 as the LO freq in your receiver setup. 

You can also use a Directv 4x8 Multiswitch to connect 2 Primestar LNBS to up to 8 receivers. These switches have 2 input ports for the first LNB and 2 more for the second that are switched on by sending a 22Hz signal. This works just fine with FTA receivers.
