[QUOTE="moonbase, post: 1056711, member: 178786"] [USER=405655]@Pipedream[/USER] I can see the issue that is causing the confusion. You have a Precision C120 transition with a rectangular waveguide aperture on the output end. The aperture size is 0.7" x 0.5" which is somewhere between WR62 and WR75 sizes. I have uploaded a couple of pictures below that show both the version you have and the version with the round aperture at the output end. The C120 transition that you have was intended to be used with LNB's that have a rectangular input waveguide. I have uploaded a couple of pictures of a Cal Amp LNB that has this type of waveguide. This type of Ku Band LNB is still available and there are quite a few on eBay at sensible prices. Lastly, if you look into the throat of an Invacom C120 LNB you can see that it is not circular. The connecting C120 flange has a circular input but after that the aperture is almost square. You should be able to connect your C120 transition to an Invacom C120 LNB so that you have quite close alignment of the apertures. After that, its a case of get it on the dish and have a scan to see how it performs. [/QUOTE]
