Its very much possible..............Because the way TS is doing all this troubling thousands of customers & Nagpal issuing public statements, it looks like TS is doing a college project...................I think Tata Sky is trying to find out the exact number of consumer count whose Dish Antenna need alignment for proper signal. If they would be activating vertical polarity, then antenna should be adjusted vertically also which may not be done presently as engineer need to care only for horizontal frequency.
By doing this activity they will get the exact number if people who are facing signal issue and for the engineer will make visit and realign it correctly
And this must be a better way than visiting all consumers home and checking the alignment
