Hi all,
my opinion, if there is space on the tower, better put antenna GSM1800 on the top, higher than antenna GSM 900 (if there is space for antenna GSM1800). ==> because of propagation
If there is no space, better swap it to dualband antennas.
For 2G system to 3G system the separation is 0.5m (edge to edge) for vertical and 1 meter separation when installed horizontal separation.
thanks
