Yes you should call a technician. Ask Him to check you Singal quality with his meter. If it is low ask him to realign and also ask him to check if the dish is installed properly. He should get 85 or above in his meter.rajkhushi001 said:bro.......I m using tata sky hd+ and my signal strength is 90 but signal quality is 40-50. should i call to technician visit.??????????
