Hi ya'll, Im a truck driver and just signed up for Directv. I am planning on taking one of the recievers on the truck with me, I have a acquired an extra dish ( this one has 3 "eyes"). I have it mounted on a mast on the back of the truck that I can raise and lower as well as rotate. My questions are: 1) I noticed this dish has a "tilt" adjustment as well as elevation and azimuth, will I need to adjust the tilt each time I stop? 2) Will this dish with 3 "eyes" work for my application? 3) I was thinking about placing my signal meter in a clear waterproof box so I dont have to hook it up each time I stop, will it affect the reception if I leave the meter attatched? 4) Any other experience in this type of application would be greatly appreciated.
