When i was doing this back in 2009 I used one of these meter made by WINEGARD model SF1000...
This produces a tone and you keep backing off on the scale as you keep peaking up on the signal...
This 'BIRD' meter goes inline with RG cable feeding the portable dish/ You have to be sure and get the DIRECTV bird and not the Dish bird... The DISH bird is due south of San Diego CA and the DirecTV bird is due south of Texas in the southern skies...
Worked pretty good for me...
