Advertisements Hi all, I'm looking forward to getting the new THR22 from DirecTV when they go national, but have a question about the dish mounting hardware and self-install. I had DirecTV with an HR10-250 until it was no longer working with the HD they were broadcasting. I had a triple-LNB dish mounted on my roof -- it's actually still up there. Here's the issue -- I have a clay tile roof and because the mounting mast is still up there, I'd prefer to re-use the mast if possible, otherwise I have to get the roofers out here and spend some serious bucks for them to mess with cutting the clay tiles and putting new lead flashing around the new mast base. Will my old mast from the triple-LNB dish work with the new dish that is required for the THR22? That would sure be nice, as I could easily do the self-install without a lot of grief and expense. I've always done self-install, mostly because I don't want some DirecTV installer crawling around on my expensive and fragile tile roof! Hopefully someone knows if the mast hardware is compatible or not. Thanks.
