[QUOTE="John, post: 1133961, member: 175005"] I was having some issue's off 40.5W with a LHC Tp that was a bit of a puzzle - i had it in my mind that it might be a matching problem of the Prodelin ribbed polariser into the AV-Comm OMT build iv'e just had a dabble with so i knocked up another transition from the Prodelin polariser using a Cband 'Single feed' waveguide. Long story short - The actual problem turned out to be my Norsat PLL lnb but the new transition seems to be a better match. A few pics of the knock up .... ...............................................................................................................................................................................................................................................................................................................................................................[ATTACH type="full" alt="Single feed mod...jpg"]144377[/ATTACH][ATTACH type="full" alt="Single feed mod..-.jpg"]144378[/ATTACH][ATTACH type="full" alt="Single Feed mod.--jpg.jpg"]144379[/ATTACH][ATTACH type="full" alt="IMG_0864.JPG"]144381[/ATTACH] [/QUOTE]
