[QUOTE="drhans, post: 987840, member: 333600"] I've tried ESX242 with the polarizer. I did cut 4 cm off the feed. The good thing was that the lnb then fitted into the polarizer just fine since the diameter decreases the shorter the feed gets. But I think 4cm is too much as I've ended up positioning the LNB in a way where cutting just 2cm would be enough. So I suggest cutting only as much as necessary to insert the ESX into the polarizer and only if you notice the signal improving while pushing the lnb further into the polarizer, then start cutting some more... My results are not representative since the LNB is placed 6-7 degrees off center, but I'd say it was worth it. I tested 40W again and I saw improvements on most transponders, in some cases by huge numbers (3980L jumping from 7.7 to 8.5 dB, 4009R up from 7.5 to 8.5 dB ). However, I never managed to find a spot where ALL transponders would be optimized. Getting a perfect signal on 3723L meant losing 3764R completely (to unlockable 9.1dB )! In the end this means one thing - everyone should try using ESX instead of Zinwell. Individual results will vary but maybe ESX will help you in getting transponders which were just below lock with Zinwell - even though other ones might be lost. I've also tried rotating the polarizer and the LNB in it. The best result I've got was unfortunately the one where the polarities were "switched" (R=H, L=V) but that's not a big deal. This just shows that optimizing the reception with the polarizer is something that will take many many (enjoyble) hours of hard work! Anyone thinking about getting the polarizer, you should still get it with Zinwell LNBF and scalar ring because you NEED the polarizer to be machined and you'll need a fitting ring. The first polarizer I've ordered was without the lnb and it was not machined which means it didn't fit any scalar ring and no LNB or OMT could be attached without hard work ...not worth saving some $80 on LNB and machining.
