Directv is coming in two weeks to install the new 5LNB dish and HR20. I have the 3LNB mounted on my 50' tower I have for my UHF antenna. Can this new dish be mounted on that tower the same way as the existing 3LNB is? I've seen a lot of guys talking about it being heavy and mounting it into a poll in the ground. Does anyone have a link to the installatio instructions for it?
