G.Low elevation issue.
Because GEO satellites are all over the
equator ,when VSAT terminal is in high latitude area, the elevation
angle of VSAT pointing is low (maybe less than 20°). In this case,
antenna will easily miss pointing with high wave so link may be broken
by this reason. In high latitude area, GEO satellite VSAT may not work
smoothly.

Now this Freq is 12721>11700,
so we need to select
LO 10600
(Plz note that Freq> 11700, LO is 10600,
Freq <11700 , LO is 9750 ),
Then now you can make calculation
as below
RX_IF 12721-10600=2121
for this DVB carrier info , plz note it
RX_IF 2121
LO 10600
POL V
SymbolRate 43200
Choose one TV signal for testing. Plz record the key figure.
Freq , Pol, SymbolRate
, this 3 parameters. e.g. 12721 V 43200
