Meanwhile I have made up images of the LNBs below:

The images below show the phase centres as being 19mm from the yoke flange edge. The phase centre of the horn should go at the focal point of the dish.

I hope this phase centre educational feature makes up for the plain advertising nature of this forum contribution. These LNBs, particularly the SX1019, appear suitable for one-way satellite internet access using 27.5 Msps DVB-S (QPSK) type carriers.
Best regards, Eric.
