Does anyone know if GSM Devices can share Aerials? If so how many devices can simultaniously use the same aerial?

Also is there a maximum theoretical length of aerial cable?

Thanks a lot!

I don't think it's a good idea...

If one GSM device is sending and the other one receiving, it means that the receiving device will get the 26 dBm tx power (up to 500 mW on some phones) on its input amplifier instead of the -80 dBm or some value around that. I wonder if the input stage can handle that without starting to smoke, which is a bad habit.

And by the way, on 900 MHz (or 1800/1900 depending on your network) you got to have short high quality cables... Check the product specs of the cable. You will find the exact loss of the cable at the specific frequency...

Good luck,
Marius
