Hi folks, I just upgraded to a hd receiver, and used my old voom dish, and could not get the hd channels as I was advised by a local vender, so I purchased a new direct tv 5LNB dish, and I can only get the one satellite to tune. I am not using a signal meter, just using the next door neighbors dish as a guide, and the directions that came with the dish. do I need a signal meter to set the azimuth? and if so how do I connect it. any help would be appreciated.
