Dual-Band 6-Port Ceiling Mount Omni MIMO Antenna for 802.11n WLAN

More InfoDocumentsSpecifications Reviews

Laird ceiling mount omnidirectional antenna MIMO for 2.4-2.5 GHz and 5.1-5.9 GHz with 2 dBi gain and 33 inch cables with RP SMA connetors.

More Information

The S2451DBT33RSM is a dual-band 6-element omnidirectional antenna for use in 802.11n MIMO applications. 3 ports are designed to operate at 2.4 GHz and 3 ports are designed to operate at 5 GHz. Housed in a compact, low-profile radome, each of the six MIMO antenna elements is connected to the WLAN Access Point via a low loss, plenum-rated coax pigtail. 

The radiation patterns are uniform and symmetrical, providing high levels signal density into defined coverage zones. This antenna will greatly enhance the performance of 802.11n systems. The dual band frequency coverage means that a single type of antenna can be deployed with any MIMO radio in the 2.4-2.5 GHz and 5.1-5.9 GHz bands. A wide choice of coax lengths and connector types are available.
