Can we use the GSM antenna or other main communication antenna to receive the FM signal? Why？ Do you have any other case like this antenna sharing?

Can you explain more clearly? The FM signal is 78M~120M, the GSM is 800M 1800M. The GSM antenna in the mobile phone can be monopole or PIFA. But I still don't know if we can use the GSM antenna to receive the FM signal?
