I have had dish for 15 yrs and installed all of them. Last fall i had dish HD installed. The tech removed the Dish 500 and installed a 1000.2 My signals for 119 and 110 use to be in the 70s. After the install the tech informed me that a tree was in the way of 129 and i needed to remove it. Spring is here and i removed it and 110,119 signals are in the 50s and 129 is 15/20. I checked the elevation and the skew, and both are off and the mount is level. the elevation is off 10 and the skew off 6. I do have a signal meter. Should i set the skew to the proper setting and realign to 119 and see if the other 2 get better?
