AT&T Mercury Booster Antennas

Boost the cellular signal to your AT&T Mercury Internet Card with and external antenna or powered signal booster system.

WARNING: Direct Connect Antennas & Amplifiers - External Antenna Adapter
We do have an external antenna adapter that fits the AT&T Mercury, however the external antenna port on the Mercury is weak and the adapter has the potential to damage the Mercury by breaking the pin inside the Mercury's RF port. This may disable the Mercury. For this reason we cannot recommend it's use with the Mercury. If you would like to use one at your own risk, use the one we have listed for the Sierra Wireless Compass.

Instead of risking damage to your device, we recommend the use one of the following wireless amplifiers that do not require a direct connection to the Mercury.
