;-)  -273 Degrees Centigrade is could enough..

Maybe? Water are Dipols and we know from our microwave oven
that water inacts with microwaves...or big snow crystals?

(How urban tales starts ;-))





But, serious, there once were LNBs where a motor turns a little wire
horizontal or vertical...if that is frozen?

But: If this would not work, you'll have no receiption at all
on the other polarization  or see the wrong channels.

Maybe
MANUAL:
  LnbSLOF    = 11700     The switching frequency (in MHz) between low and high LOF
  LnbFrequLo = 9750      The LNB's low and high local oscillator frequencies (in MHz)
  LnbFrequHi = 10600     (these have no meaning for DVB-C receivers)
