located    135    degrees  programmed    ses-22   into   antenna positioner.  checking  daily for  any  rf  signal  from the  new  satellite  to show  up  on
spectrum  analyizer.    web  searching  for  any info  as to what services  might be moved over to the new  bird.

i noticed  what i beleive is   5 ghz  cellular  at 3820  mhz   extending  to 4200  mhz. while  on    135  degrees. then i moved the dish az  and  el  does not change the steady  terrestrial  5 g signal.   took  a spare  c band  lnb  into spectrum analyizer  held it in  my hand  still  getting  signals  3820 and above  does not matter much on polarity of the  lnb   waveguide.   if i put  a metal plate across the front of  lnb  signal does  attenuate.
did some quick research....by  2023   new   cell  band  will be  from   4000  mhz   to   4200  mhz  so  any  satellite signals  above   4000  mhz  will get interference.  going to  go take a look  at any  lyngsat  listings  for  satellite signals  above 3800  mhz  to see if  they are  affected  by  the  new  5g  signal.
i see  the  wx  channel  is in the clear on the  mux  on  amc-11   3780  mhz     30,000  sr   going to go take a look  soon.

correction....any  signals  below   4000  mhz   would be out  of  the   new  5  g  cellular  allocation   at the  end  of   2023 .....but  if  the  signal  is  near  4000  mhz  it might get  zapped  by  the  new service  guard band  so  a  filter    to  clear out   4ghz  to    4.2   ghz   or  lnb  that  will reject   might be needed in  high density metro  areas.
