Old site from the TACS and GSM days?”
However, I found a big book about GPRS in a library somewhere which explained why having 3-4 GPRS antennas was a good thing...It was something to do with polarisation and diversity. Infact, on the planning application for the mast, it said 3xGSM 1xUMTS per sector, so the 3x900 panels are all for GSM900. Also, this mast is fairly new, 2003 ish, long after TACS
Probably 2xreceive, 1xtransmit
