[QUOTE="canofan, post: 501312, member: 259756"] How sure are you about this statement? have any measurements been made or experiments in that direction to challenge the Invacom 0.3db noise figure? I appreciate very much this quantitative analysis. It is not mathematical but almost. As a result of the foregoing analysis: 1-apart from a possible experiment with the Invacom QPF-031 coupled to a 611-6060-10 feedhorn, and in case this experiment fails to give the expected results. 2-and apart from tryng to implement a chaparal corotor by finding a way to manually or automatically rotate the LNB to the proper polarity. One should consider using two smaller dishes for the Nilesat: one for horizontals with 611-6060-10 and Norsat4206A and the other for verticals with 611-6060-10 and Norsat7707A or NJR2744H. It is possible to find used smaller dishes, so that should reduce the outlay and the whole thing will be less expensive than a bigger dish. [/QUOTE]
