The main component is the correct LNB to go along with Your Receiver! You will need one of the earlier series receivers and LNB in order to use a Round Dish. The Later series 600 Receivers require an Elliptical Dish with an adjustable Skew!
I should have added that We have gone through Three different series of Shaw/ Star Choice LNBF and Receivers.
The Earliest one had a Skew Adjustment right on the LNBF. They used an almost Round Dish which was slightly Taller than it was wide!
There was a second dual LNB unit which We upgraded to that used an elliptical dish
The Later Elliptical Dish came with the Second Series of Receivers ( To Us ) the LNB has 2 Horns and 4 outputs and was then a Fixed item and the Dish adjusted to correct the Skew.
The Third Series uses a Triple Satelite LNB with 4 outputs!
