Hi all after some advice please.

I have a old sky dish with a single LNB
I am looking to change the lnb to a quad.
The site sponsor suggested that I change the dish instead and recommended a dish which comes with a quad LNB too.

Now i can do the hardware bit of fixing the dish to the wall however I am not sure how I would align it or how much of an issue this is.

I plan to install this next to the existing dish and then remove the existing dish.

Do i need a Sat meter or anything?

any help would be much appreciated

Thanks

Bart
