[QUOTE="blademedia, post: 1019038, member: 409057"] Hi moonbase, Yes the larger dishes have a very tight beam width, it can be time consuming getting it to track correctly in KU band as you will know with the 2.2, C band is more forgiving, The Research Concepts RC2000C dual axis controller is perfect for the job it also controls the skew which is very important with AZ/EL, Personally I don't think a 4,5 inch pole is big enough for a precision dish over 2.4 but you can check up on that and I will make the mount as instructed by you, Once you have the measurement's and we agree on a price I can start fabrication, I will only be able to work on it in my spare time, it could be a few months before completion, since ive retired I have less time on my hands than when I was working full time, There are various slewing rings on the market, once we are in agreement with fabrication costs I will give you a list to choose from, there the type of item on a mini digger that turns the cab, Both chain drive and slewing rings are free from play, the gearbox ratio will be up to you I will give you options for this, the higher the gear the slower the dish will move, it can be geared in two ways actuator and gearbox, Most people try to alter the pulse count that's totally wrong, the way to make a dish more precise is the gearing, Btw what size dish is it ?, I will look forward to making this mount and seeing your installation progress.
