Hello all, I have to clarify again. What I am concerned here is not the number of users, but the power that is fed into the combiner before blowing it. Yes, like what waleed said, the combiner is supposed to receive and transmit without damage. But there will be a max power input per port of the combiner, e.g 100W, etc. So we must know what is the PEAK power that the BTS will transmit.
