Are you suggesting to use a "SPLIT2P-SMA" for that purpose? I'd strongly discourage, as you would still get a lot of Tx power leakage from nanoBTS1 into the amplifier of nanoBTS2. I doubt that they would like that. The alternative here really would be to use one of my hybrid combiner/duplexers in place. We simply ignore the Rx path and use it to combine the Tx path of the two BTS before feeding into the amplifier. > We have two omnidirectional antennas from PROCOM: CXL 1800-3 > More information: [3] > > >Also, when would you be able to provide the equipment to me?

I think we would definitely like to make use of your 2 nanoBTS boosters, even if we can only use each of them with a single TRX setup.
