I know this is probably a very basic question, but I have been scouring the internet to figure it out and I am getting a bit overwhelmed. I wan't to install a dish myself. On my Condo Balcony. I have two Hr24-500 DVR boxes and will likely add a 3rd HD non dvr receiver. What direct tv equipment do I need to buy online? and if someone knows a good installation tutorial video for mounting the dish please let me know. I am in the greater los angeles market, and have a clear view to point my dish in the correct direction. Thanks everyone for your time.
