I observed very good signal of DTT transmission in Flight during My tour to Delhi on 1/5/16 and also on return journey on 4/5/16The signal of DTT transmission from DDK Ahmedabad was available upto 140 Km from Ahmedabad in the flight; I recorded some clips of DD Girnar and DD news signal upto 8:15 AM, after the 20 mints of take off the Flight on 1/5/16.Similarly on return journey on 4/5/16, the signal of DTT transmission from DDK Ahmedabad was available upto approx 148 Km from Ahmedabad, in the flight.
One Interesting thing is that during passing over Jaipur to Kota, I retuned the my dongle on mobile phone, I observed the signal of DD Madhya Pradesh (a booke with DD MP,DD Kisan,DD News, DD sports,DD Bharti,DD National) at 4:55PMon 4/1/16 ,probably the signal is from DTT transmission of DDK Bhopal (aerial distance approx 250 KM).
The above observation is interesting and with the DTT, the DD channels may be available to passengers during their flight journey on the LCD screen in Aeroplane, The passenger on flight can also enjoy the live activity of ground.
The Video recording of signal with photographs are attached herewith.
