Different LNB versions need different routings. Use tape to isolate PCB tracks.<\/li>\n\n\n<li>At the intermediate frequency connector, remove the printed inductor (PCB-L) and replace it with a 2.2&ndash;4.7&nbsp;&micro;H ferrite bead. Make sure the ferrite bead&rsquo;s resonance frequency is far away from 400&ndash;800&nbsp;MHz.<\/li>\n\n\n<li>Test with an external power supply and LO.
