This means you have many parameters that need to be tuned: dish alignment and LNB alignment!<br />Also, note that C-band requires a much bigger dish with 1.5m being normally the smallest recommend size. While it is possible to have reception with 0.9m dish, that is considered DXing and requires extra fine tuning and luck.<br /><br />Regards,<br />Vitorvmahttps://www.blogger.com/profile/09121699091696526309noreply@blogger.comtag:blogger.com,1999:blog-3388331926569820194.post-12952747461520405562021-09-25T10:01:13.713+01:002021-09-25T10:01:13.713+01:00C-band reception in the Netherlands: I have a VMA ...C-band reception in the Netherlands: I have a VMA and an offset 90cm , a chinese 15K c-band lnb (without dielectric plate) and Dreambox DM800<br />Via Ku-band I try to point out the dish for i.e. SES5 (Ku+C-band) however on C-band I haven't seen even a signal-rise for reception. Can you suggest which sat with c-band to receive (relative strong transponders for 52N, 5E)? And how can a dielectric plate made by you own?
