[QUOTE="John, post: 1052571, member: 175005"] ... when the ODU arrives you will need to do the following mechanical tweeks first :- See pics Separate the feed / poloriser / ODU from each other. Put the poloriser (middle bit) in a cupboard as not needed for Newsnet linear signals. The scalar feed has to now be married up to the opening on the ODU. As the above is not a standard Gilat configuration it means that 4 more holes have to be drilled in the feed output flange with a good degree of accuracy so that the feed circular throat matches identically up to the ODU front throat opening. You then need to make a 40mm collar to fit over the feed so as to fit onto the dish lnb holder - - when you have done the other bits first i will go on to show you what i did to make the collar. What's been detailed above is the very easiest approach to doing the mechanical feed alteration but does not give you any adjustment for tweeking the focal point of the feed - it gets you more or less right but unable to tweek back and forth for max. .................................................................................................................................................................................................... s-band Graham has done more work on these 8002 ODU's both electronically & mechanical as he's the guru on these things, so need to ask you Graham- will the 8002 see 18.556 in bog standard untouched condition ? - - just trying to keep the operation as simple as possible at the moment. ........................................................................................................................................................................................................................................................................................................
