Reverse LNB Polarity

[trinidex]

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?

Thanks

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.

They do vary from model to model, however, some are 5/6 volt and some are 12 volt, and I think that some of the Drakes had the plus ion the shield and the minus on the center conductor. I installed four of them at a Cox cable headend so that they could receive Ku feeds of a Bullseye, dual C/Dual Ku feed that I also installed using their own, residential-grade Drake receivers, and I had to put in discrete LNB powering supplies and voltage block them from the switches to make non-Drake switches work with a Drake receiver.

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.
