Reverse LNB Polarity
I have an 8ft offset solid dish with a Ku LNB mounted no the end. The LNB is bolted to the arm, not installed in a collar.
The polarity of the satellite I want to receive is reversed, so H is V, and V is H
Is there a product that can be installed in line, that will reverse the polarity?

I want to know as well.. because that would solve dish pro issues with toriadol dishes..
Lots of companies make external H/V switches that are toggled by an accessory port. All you would have to do is swap the two input wired.

The good news is, almost all of them are the same, so for twenty bucks of less you can buy one and try it. Back when I did that installation for McR, I found them somewhere really cheap, like about $6 each, but I don't remember where.
This remedy could not be adapted to a Dish Pro Plus single coax output.
