Has any one used a signal combiner / signal splitter before? What is your verdict on such device? What is the down side of such device? I have 4 clients dispersed around my AP with the furthest about 2km away. The Omni antenna was not giving very good signal. A sector antenna could cover the most 2 clients so I am think of using Yagi for a more focused point-to-point link to each of these clients. A signal combiner sounds like a good device if I don't want to have too many AP. I would like to hear from someone who used a signal combiner before before I make the decision on whether I should get one. Thank you.
