[QUOTE="tony smith, post: 1031808, member: 402577"] Hi s-band I would say that the vertical signal you can see at18.794 is part of your block down convertor process showing up as low level image like old heterodyne receivers did. Otherwise it's as the satellite frequency plan. Satellite beacons as not the most reliable part of the space crafts kit, I have not seen one on any of the Lockheed Martin 2100 birds at 19.2 east, even with the R&S spectrum analyser, they can be very narrow, band none modulated of course, also by nature low level, unless you need them for your beacon receiver, then all identification can be taken from satellite's data. The 18.405 frequency you called as a beacon, I think again is locally generated, as it's part of Ka 5 Germany zone beam 5, so would not have a beacon there, if it was active Also looking your antenna, it's fine for Ku and K bands, I would make your own oblong feed horn, as your made for Vsat feed, is not helping with all it's stud filters. they are very easy to make out of tin plate, to get all the size info and details just look up some made up units on internet and many makers give the measurement details, I have made quite a few this way, they work fine fitted to WR75 type flange or smaller flange.
