Reading that diagram: What ist the "combiner" ? 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 would
want to put everything together + test it well ahead of the camp,
probably around August 1st.
Ok, I will see what I can do.
Has there been any news on this? 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.
Regards,
Harald
