SP9VFD Raf I am just discussing with the company b.e.s.t. in Germany. They have rocket LNBs with PLL!!!
If you disassemble the plastic enclosure the diameter will fit into the helix. Will get some information from them this week and will post it here. the most issue is to find a dish where the position of the LNB is more away from the boom as usual. for examle here a picture.
With this it is easy to fit the reflektor for the helix. I have ordered a dish for less than 16Euro including S&H.
