Recently we had Direct TV installed in our house. I wanted to be able to use satellite TV in our truck when we are stuck somewhere so I got an extra dish and receiver to take on the truck.(Yes, they are registered with the company) I have never set up a dish on the road so I thought maybe someone out there could help. I do know enough to supply the zip code where I am and that supplies me with the info I need to aim the dish. I have a compass so I can figure the direction pretty close but can you tell me the difference between "elevation" and "rotation"? I only come up with two things I can adjust. Am I missing something? Also, on the dish connection ( the arm, I don't know the proper name) there are two places to screw a cable into. What is the second one for??..And hey, before you tell be to check my directions which were in the box..you guessed it.. I'm out on the road and I left it at home. Any help would be greatly appreciated. Thanks in advance for any help you can give. .... Well, the phone just rang and we're gonna get out of here with that next load.. Thanks..
