Hi Guys, I need help. I have a DishPro 500 Dual LNBF dish feeding a 311 receiver on my boat. I mount the dish on a fixed piling. I recently moved the boat to another slip a few miles away and re-mounted the dish. But, now I am getting satellites 119 and 129 instead of 119 and 110. I get absolutely NO signal on 110, but then both sides are occupied by a satellite (119 and 129). I have read other messages posted here and suspect I may not have the dish plumb, or somehow not aimed right. Also, maybe I need to unplug the coax and do a check to clear out the system before I start over. What are your suggestions? By the way, I get a strong 119 signal, over 100. Thanks for any advice!!
