AT&T Beam 340U Antennas & Signal Boosters. Boost the signal strength to your AC340U to improve Internet speeds.

The Netgear Beam 340U is a MIMO device that has 2 antennas ports. A MIMO Device used 2 antennas to send and received a signal at potentially higher speeds. MIMO technology is controlled by your service provider and may not be available in your area. If not available, only 1 antenna is required. To achieve true MIMO purchase two adapter cables and 2 antennas (or one MIMO antenna - 2 antennas combined to 1 package with 2 cables). To achieve the best performance make sure the antennas are 18" apart or greater.

The 340U supports an external RF antenna for use in increasing the strength of the Beam's network connection. To install an external antenna:

• Remove the Back panel on the Beam 340U by pressing on the cover and sliding away from the device. 
• You will see two ports at the base of the device. 
• Remove the External antenna cover from the desired antenna port, then attach the external antenna. 
• Replace the Back panel by placing it over the device and sliding until the panel snaps into place.
