The polarizer is contained in the LNB. So you only need an LNB with circular polarization. If that LNB is controlled with the same signals as common LNBs with linear polarization are (where +13V sets vertical polarization and +18V sets horizontal polarization), you can use the same drivers without changes, and only have to know what circular polarizations horizontal and vertical correspond to.
