OK so for the first time ever I tried C-band on an offset dish (prodelin 2.4m) but I'm disappointed with the result. I can't get a better SNR that I'm getting with a 1.8m PF dish.
I wanted to get the new Startimes muxes but no matter what I did in terms of adjusting the LNB position, I can't get over 7.1 dB on 3725R. In Ku band, this dish performs well, I get at least 2.5 dB more compared to the 1.8m PF, so why can't I get the same 2.5dB more in C-band?
So I wanted to ask if someone has an experience with C-band on offset dishes, if it's normal for it to perform not as good as a PF. Or could it be the fact I installed the dish upside down? Or is the scalar ring from ebay crap?
Here's my scan of 8W from today. Note - the polarization is swapped! Also attached a picture of how the LNB is installed.
