I just got an Invacom OPH-031 to put on my 90cm Fortec dish. When I opened the box and held the Invacom, I couldn't believe the weight. So, what I want to know is, is this LNB too heavy for the arm on the dish. I read a lot of good things about this LNB and hoping to see if it having higher gain improves any weaker transponders. I have a Tracker II now which I like but one dosen't know what one likes until one tries all the others. This FTA is a sickness..... is there a cure?
