HWIC-3G

Will a 50 ohm load on the antenna port sufficiently drop the received signal level?

For a test, I have an HWIC-3G-CDMA card and an HWIC-4B-S/T card. The BRI card is connected to a satellite data terminal for an ISDN connection. The 2811 router is connected to the cellular network and I want to check the fail-over capability to the ISDN connection. I have been able to disconnect the cellular antenna and the received signal drops to sufficiently fail over to the ISDN connection. However, lately my received signal is great enough that even removing the antenna doesn't lower the received signal enough. Will a 50 ohm load/termination work on the antenna port? Or would an RF antenuator be better?
