[QUOTE="Old Satellite, post: 15282, member: 175277"] A magnetic polariser is used to adjust the incoming signal from the satellite it is normally on a C120 flange. There are still many shops has to where they can be puchased . The problem is that they need from the reciever a magnetic output tyipcally either 50 MA or 100 MA at 5vdc- none of the standard digiboxs are able to provide this output. Plenty of the old analogue recievers had this facillity as standard and can be ontained for a few pounds- but then you would need to use two recievers ! not so easy The advantage is with a magnetic or Mechanical Poleriser is the ability to adjust the skew with greater precision. they can still also be fitted to a majority of both offset and prime focus dishes with a small modification. you can then also utilise a PLL ( not cheap) specification LNB to best effect . LNB options if you still wish to continue in this direction you could also try talking to SMW in your area and highlight that you are conducting a test for reception and ask them to provide you a matched specification lnb - they may have good response to this ? HOWEVER, sorry to highlight once again but even this type of modification you would still be unlikely to provide the increase in signal required to resolve your signal reception problem on Astra 2d, the only assured way is to increase the size of your dish.
