Sylvain -- try the FA-SY 1. It's cheap and fairly easy to install.
(It's not something that you could calibrate and leave on a tower for any length of time though. It is strictly an "experimental" type clock.)
Quoting David A. Burgess (dburgess@jcis.net):
You will most definitely need an improved clock to operate in the 1800 band.

For info:
Ok, I called the IBPT and I got the procedure to follow to request frequencies.
The 900 MHz is entirely allocated to commercial operators but in the 1800 spectrum there are possibilities to get experimental licenses for a small fee so I'm filling up the paper work ASAP.
For OpenBTS to work in the 1800 band we may need more stable clock source (which I don't have yet). For OpenBSC, I have a 1800 nanoBTS.
