Searching Satellite Signal

I did not intend to write anything today because I am watching CSI:Miami on Ture Vision. But rain and thunder storm make UBC fail to broadcast its programs and the word "searching satellite signal" appears on screen. It always happens when it is going to rain or raining. My friend told me that it was cause from the satellite they use does not directly cover Thailand. I do not know exact reason, however, if it is not in Thailand , they may have been sued.
