Try this....
Disconnect the Actuator at the Dish and "carefully" flop the Dish to 1 side. Make sure the Actuator is out of the way!!!! Don't let it fall!!!!
String the Dish where the Panels are joined tie string tight. Then use 2 pieces of small string, and string the back of the Dish, tape the string in the grooves where the panels meet, so that the string forms a Cross in the hole of the center plate. Make sense so far?
Now, from behind the Dish, look thru the Center Plate.
Is the Feedhorn in the "crosshairs" of the 2 sets of strings?
Even pop the feed Cap off for a better view.
The last time I did the string test I did that,but I didn't disconnect the actuator.I just moved my dish a little past 137west and was able to see the string cross and the lnb from the back. Plus I use a laser pointer on 4 sides of the lnb to help point it at the center. I'll have to try to roll out the dents in the mesh. Thanks Again for all the Ideas. It's all well appreciated:up
