[QUOTE="John, post: 1165377, member: 175005"] Re: lnb caps , there could be around 1/2 a dB or so lost through some caps, not a problem if your only looking at strong satellite signals but very important if your a Dx'er. If i try out any new material for an lnb cap I always give it a microwave oven test ... ie 15 to 20 seconds or so , feel or test material for a temparature guide, remove after zapping it and it should be the same temp coming out. If it shows a rise in temp then it has absorbed RF which is what you don't want especially if it's an lnb cap looking at a DX signal. I'm using RF transparent film over my Ka and Cband lnb's on the 2.2mtr, still have to change the Ku lnb cap though. CCTV camera shot of caps. ......................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................
