[QUOTE="a33, post: 1134399, member: 332642"] I found the post, where an LNB inrush current of as much as 2700mA is reported: [URL unfurl="true"]https://forum.digitalfernsehen.de/threads/neuling-hat-lnb-tv-kuriosit%C3%A4t.391836/page-2#post-8234951[/URL] A resistor could work, and you would have a choice to put that at the receiver end (involving all current-receivers), or at an individual current-consumer ("the culprit"). I've also thought about using a coil (with a diode anti-parallel, for protection?) and a capacitor. No idea if that would work better. Ideally, the receiver power supply should not be able to supply such a peak current, I would say. So that the coil (+ diode) should ideally be at the power supply? Not sure what effect to expect from a .1 ohm resistor, as [USER=369937]@Terryl[/USER] described. Seems a very low resistance value, compared to a possible 2700mA...? Greetz, A33 [I]Edit: I also found a post by @raceroad where he tested the difference between using an electrolytic capacitor, or a ceramic capacitor in an LNB: [URL unfurl="true"]http://www.hifi-forum.de/index.php?action=browseT&forum_id=97&thread=20750&postID=4#4[/URL] It seems the latter is better. Don't know if he exchanged them himself, or just compared different LNB designs. It seems to be the latter...[/I] [/QUOTE]
