[QUOTE="moonbase, post: 1064423, member: 178786"] Agreed, it seems to be a simpler option and possibly a cheaper option to purchase a dedicated off the shelf LNB that is designed to operate in the 4.5 Ghz to 4.8 GHz range. All that needs to be done is bolt the LNB to a WR229 flange feed and fix it to the dish. Norsat offer several types of LNB that meet the need and there are also the Chinese LNB's.
