[QUOTE="ynot62, post: 147386, member: 176787"] Hi Guys, I am back. It has been 18 months since I bought my Patriot Az/El 3.8 mts prime focus dish and still the bloody dish is working not better then my other 1.5 mts offset dish. I have two Invacom LNbs 0.3db C120 , a twin and a quad; My feedhorns are the ADL - KU 850 and ADL - KU 855 both supplied by Patriot. My F/D is 157.2 cms as Patriot itself told me. We checked with two strings if the dish was distorted but it seems ok. One day we just put a foot on one petal very close to the centre of the dish and the signal on Astra 2D went up quite a lot. Yesterday I was reading once more the Install Manual of my Dish and I noticed for the first time that on point 8 regarding how to assembly the petals, it says: Starting at the hub tighten all hardware by working outward 1 circular row at the time. Actually we never followed this procedure but layed them one at the time screwing them to eachother as we went alone. Could it be the reason why is not working properly? Maybe we distorted the petals or the alignment is not proper? If I retighten the dish again could i solve the problem? Or should I buy a new LNB ( like Inverto or MTI ) or Feedhorn or both? What about this new adjustable feedhorn ADF 120 by Invacom, and if I buy it how can I match it to my dish? I wouldnt have the right mounting ring. Ok thats all for now Regards Tony [/QUOTE]
