Two UTD's off one antenna?

[BBReaper]

Has anybody tried connecting two UTD's to one hi-gain antenna? Is it at all possible?

we have a GSM concentrator which allows us to connect 8 GSM modules to one external antenna, so it should be possible. i do know that it does require some electronics.

Dont forget the added signal lose, a combiner will cost you anything from 10-20dB
