As per in subject, I would like to know if there is such a thing as a Diseqc switch with 2 feeds instead of 1.
Until now I have not seen one for sale but I thought to ask the experts before giving up.

I currently have 3 LNB Setup on a dish with a switch with one feed only for one sat decoder.
I would like to have another feed available for other sat boxes to perform some tests from time to time.
I know that Disecq switch cannot be controlled twice simultaneously but this is not a problem as I do not intend to use two deoders at a time.
Is there anyway to split the feed from the switch instead of replacing all three single LNB'S with Dual Feed ones?
