I have a camper too so maybe i'll get a portable sat setup and use the meter for that too.
Mast is very plumb after lots of work to make sure that is the case. I'm not at the property currently so don't have full info but here is what i know...
Can't remember on the elevation but did what the instructions said and then went up and down tiny amounts to get the peak reading on my tv screen inside. Spent hours doing this multiple times with one person outside and one person inside watching the levels. Not sure on 103 but believe i'm getting all of the channels i should be getting except for the locals. Readings for sat 101 are in the picture below.
There is a small dent in the dish that was just noticed by my Dad. Not sure if that would cause us to lose only the local channels but ready to pull my hair out so thought i'd mention it. Tried adjusting the tilt and couldn't get more out of it than the starting position.
