[QUOTE="Spiff, post: 1011657, member: 404998"] Good afternoon Moonbase from a sunny Mullion Cove Cornwall. Thank you for taking the trouble to send me that link : ) It is a nice simple solution, I wish I had thought of that. I went ahead with my original plan and apart from setting fire to myself with sparks from the grindstone ( Alanna said it was going to happen but I would not listen ) all is now installed. I have just finished tidying the wiring and am about to replace the USB to cat5 camera feed with USB repeaters as they work a lot better. The camera is to view a scale on the mount, I also have two on the KU band mount. I have taken photos along the way, including the fire : ) and will post them later. I am now about to work on an idea to rotate the C band LNB polarity insert by motor so as to switch between right and left hand circular polarity by remote. The idea is to drill a hole in the rear of the LNB and put a shaft through the length of the LNB with the insert on it. The water / insect cover at the front will suspend the other end of the shaft. The insert with either have to be cut down to turn inside the locating slots or the slots will have to be ground off. I do not know if reducing the size of the incert will reduce its properties ? Also what sort of material to use for the shaft, metal may not be good, perhaps a hard plastic knitting needle. A cog could then be fitted to the rear end of the shaft and a small motor to drive it, perhaps using parts from an old video recorder. A thicker piece of material at the rear end will also give the shaft more stability. All this is so that I will not have to send Alanna out on cold winter nights to change to polarity : ) God Bless Spiff [/QUOTE]
