Hi

I have one TV in my living room and want add a second TV in the bedroom,sky channel I have,coul any one tell me how to add a second TV

I assume sky channel is a satellite service. If you want to be able to watch different programs on the second TV, you will need a second settop box from the service. They will explain how to hook it up to your antenna.

Yes it really depends on how you get TV to begin with... if its sat you not only need a second box but a second LNB...
