[QUOTE="moonbase, post: 1086369, member: 178786"] Hmmm, I am not sure about the feed arms for your 3.7m dish being the same length as those for my 2.0m dish? The Precision Antennas catalogue lists the focal length of your 3.7m dish as 1207mm whereas the focal length of my 2.0m dish is 755mm. If I remember correctly I think the original Precision feed support arms for my 2.0m dish are 998.5mm, from your picture it looks like your feed supports arms are 1490mm? What you can do is to measure the length of a feed support arm that is on your dish from the dish face to the scalar clamping collar and subtract 80mm from that length and get the shortened length made up as the stainless steel pipe part of the adjustable feed support arms. The adjustable screw threaded extension rod at the feed end can then be used to make up the shortfall. I think when I got mine made up by Rima I subtracted about 90mm from the length of the original Precision feed support arms and got the extendable threaded rods at the feed end made to 150mm to give me plenty overage. The other point to consider is the internal thread sizes at each end of the stainless steel pipe part of the adjustable feed support arms. I had mine made with M10 threads at the dish face end and M8 threads at the feed end. This allowed me the option to fit a Precision Ku-Band feed which has M8 internal threads that the feed support arms secure into. The M10 threads at the dish face end matched the specification of the original feed support arm securing bolts. You might need to measure the internal diameter of the 3 press stamped holes on the dish face to confirm an appropriate thread size? If you have no plans at all of ever fitting a Precision Ku-Band feed to the dish there is no need to adhere to the M8 threaded extension rods, they can be whatever size you choose to fit your co-rotor clamping collar. I had the clamping collar made up with 9mm holes on the 3 legs to give some slight adjustment with the M8 extension rods. One thing I can probably say with certainty is that you will be delighted with the quality of the parts you receive, they look good, are well made and represent great value for the price. [/QUOTE]
