every beam has a footprint it covers...
If tp changes beam, d chnls would not come in the specified region.
for eg: 12710h is currently on North asia beam, covering Indonesia... if tp changes beams, ppl in Indonesia will not get to see their fav chnls...
Now, the parameters can be the same... on two different beams, thats a manual entry...being made by someone in their techincal team :k
