thanks for reply Pix.
I am in a situation where i have been given these antennas which were earlier being used with a CDMA BTS.
Now i have to use them at a GSM site.
As far as my understanding goes antennas are passive and nothing to do with the technology radiated through them.
In order to find out whether my frequency band of GSM900 will work ok or not with these antenna can i use the
VSWR testing method?
