If you want to spend a lot of money, you can buy a CPR229G flange tee plus a second LNBF for the other polarisation. But the LNBF alone would be around 250$. I guess there is no CPR229G dual polarity LNBF.i googled for such dual-polarity LNBs, but could not find any. I know they exist in Ku, with a C120 flange (Invacom, Inverto), but have never seen them for C-Band
DL10M, do you know if that's an adaptation, or is that LNB available on the market with that flange?
