[QUOTE="RimaNTSS, post: 898736, member: 312276"] LNB has only one Focal point. I think it is where I marked red dot on the picture. And even IBU or other LNBs have long neck it does not make any sense to tweak LNB closer/further from to/from antenna. If you move it closer to antenna, than it goes out of focus and antenna's elevation should subsequently be adjusted. Basically, Red dot of LNB must be placed instead of laser diode, which is exact location of antenna's focal point. Only one, proper position, other ones will be wrong ones. [ATTACH]68346[/ATTACH] Questions are OK. There is only one stupid question - Not asked one! :rolleyes: [/QUOTE]
