I figured it out. The dish has to be re pointed using the on screen meter. If you are going to take a stab at it yourself do it very carefully.
Mark dish so you can go back. We used a sharpie.
On screen meter takes a few seconds to respond. Be careful !
Move dish up down left right gently don't bend it with bolts still tight.
This one needed up and we compromised at 50% you can get more but you will screw up 129.
Signal will change when the bolts are tightened. We ended up with 53% on 118 and 60% on 129 same trans. It took a long time to get this balance. You give some to one you take away from the other so you need someone inside as well watching the meter.
Very poor design compared to other brand.
Took an hour for a 5 min job.
Don't blame your installer. The design of the dish is at fault.
