Dialog Satellite Television operates on a Ku-Band frequency, which is a very high frequency at 12 GHz. Employing such a high frequency has both its positives and negatives. The positives include high quality video and audio transmission with little interference and the ability to use reception equipment that is small in size. 

The negative aspect of the high-frequency KU-Band is the short length of the signal that is sent from the satellite to the reception dish, which cannot penetrate heavy rain that blocks the signal path. This problem, which is known as “rain fade” is endemic to the usage of the Ku-Band frequency, regardless of which country it is used in, although countries in monsoon zones are more likely to be affected. Interference from rain, however, should be limited only to short periods, after which the system will search for a new signal and normal viewing will resume.
