Convert Winegard to dual LNB?

[eadien7]

I have dish network programming and bought the portable Winegard PM 2000 dish with a single LNB output for use in the RV. (wouldn't let me post the link) It is a round dish. Can I convert to a dual LNB with in order to pick up both 110 and 119 or do I need a whole new dish? I've seen adapter yokes, but not sure it will work with the round dish.

If I need a new dish, seems the non-portable ones are more affordable--can I rig up a tripod or stand for a regular house dish?

You can screw around trying to adapt your Winegard, or get this from one of our site-sponsors.
It's a Dish 500, with DishPro two-bird Twin LNB assembly.
Put it on a tripod, or a 5 gallon bucket full of cement.

If you have a non-DishPro receiver, there is another similar model you could get.
It has Legacy Twin LNB.
What receiver do you have?
