Manuel, it is a cheap no-name c band lnbf. The dish is exactly the same as yours but with the mount to put an actuator mine is fixed at Intelsat 805 for now until I get an actuator and a vbox or gbox.
I was receiving Pantel without any problems a now the channel is gone. All other channels are working fine. I have a fixed 2.4m dish with a chaparral lnb.
