Good morning,
I would like to use two directional antennas with a nanoBTS DCS1800.
As far as I know, first I need a duplexer to use one antenna both for RX and TX
- does anybody know a cheap model? I found only one for 500 Euros.
Second, to connect two antennas to the duplexer, I need a power splitter.
Can somebody suggest one for duplex usage?
Third, to improve indoor signal level, there are plenty offers of duplex
repeaters, but the legal situation is unclear because one might produce
distortion on ARFCNs different from his own. Again, anyone with experience?
Maybe a suggestion for a model with a fixed ARFCN setting?
Thanks,
Lennart

The nanoBTS-Booster from Proximus has an integrated duplexer + HPA and
LNA. I have two of them and they work great.

But in the past a loot of people tried to contact Proximus without
success. The price for one Booster is about 1300 Euro.

Some days ago I looked at the legal situation of broadband GSM repeaters
in Germany. At least in Germany there is no way to operate such a device
if you are not an operator.
If you find an repeater that operates only on a specific ARFCN and you
have a license for that frequency than it may be legal to operate such a
device.
