    I am a full time RV'er and have a roof mounted dome SD dish and I also have a Slimline dish I use for HD reception when I spend several (+) weeks at the same campground. Both are dual LNB's.

    The question: is there some sort of A/B switch where I could have the wires permanently connected and just push buttons to switch from one source to the other, instead of removing the receiver and swapping the input wires from one source to the other?

    You'll need to check the RF frequency range on such a switch.

    Much of the equipment set up for switching TV antennas isn't rated for (or doesn't pass at all) DC power at the amperage required to power the LNB assembly.

    Bottom lineis, NO, there are no a/b/ switches available that will allow you to switch between Sat dish's, as you must send both a dc power componate and a rf componate to the lnb and must switches are made to block the dc and must will only pass up to about 600mhz, where you need to pass at lest 2.1gig herz.

    Guess I will just run some long pig-tales out the back so I don't have to remove the receiver each time.

    Thanks for the reply's!

    May be the best option as this: http://www.amazon.com/Remote-Control-Satellite-Selector-Switcher/dp/B0042QCLQ4

    Doesn't have any more information as to what it does and doesn't do.

    Nah VOS ... not even close I'm afraid. :)

    I got one of those from Radio Shack as a Christmas gift back in the 90's :lol:

    And it can't switch satellite dishes. The Amazon listing is not correct, it's electronically the same as any cheap mechanical A/B switch but with IR remote control. I used it at the time to switch between the ch. 3 output of an old DIRECTV receiver and an OTA antenna for a TV that had no direct A/V inputs.
