Good Day,

I have an 8.5 ft spun aluminum solid dish.. I originally aligned this dish in the mid-00's.... At the time, I had much more moderate luck with ku ... So I went to a c-band only corotor....

I typically get c-band scans like the attached image... So I believe the dish is aligned well... Have others had success with both c-band and ku band on a dish like this as described above...?

Thank you for your feedback...

I would say in general with any dual band feed it is probably a compromise.
Can either peak the feed for optimum C, or peak for optimum
Ku, but may struggle to get C and Ku peaked at the same.
You may find where they are both "good enough"
For you though.

Fellow Members, your posts are welcome here! Do not worry about posting everything perfect. Different receivers and LNB's will give you different Frequencies and Symbol Rates. Some set top boxes, PCI cards and USB receivers, Do Not Require all of the same information that others may need. It is not Required to post everything that others may need to tune in a feed. It is just most important to share the find. We can always adjust the Frequency and Symbol Rates and try the various Modulations and FEC's on our own receivers until we get a lock and then give a polite reply with what works for your receiver, as that information might help others as well. We all appreciate the efforts and energy of the Posters!
