Not sure if this is the place to post this if not where. Very green I was just given a project to expand the hospitals internal cell coverage. Currently we have only half of our first floor setup for coverage. Our setup is pretty basic at the moment, we have an omnidirectional antenna on the roof, which goes to an amplifier repeater, which then feeds 4 Wilson dome antenna. We'd like to add another 4. I guess the vendor sold us this system and told the director it would be easy to expand, all we would have to do is run the coax 400 to more antennas and that was about it. I spent some time looking into it and it appears this is our unit http://www.ibwavecomponents.com/?manufacturer=Cellular Specialties, inc&model=CSI-DSP85I-C/P And it looks like it can only supply 4 feeds antenna. So I was wondering can the line from the omnidirectional on the roof be split to a second amplifier? Do we have any "easy" options for expanding? The vendor is trying to sell us new equipment from ANDREW called iON and we just need basic repeater functions.
