A2503S3_O - Multi-Band 2_5-4dBi Omni MIMO Antenna

Multi-Band 2.5/4dBi Omni MIMO Antenna


Descontinuado: Producto no disponible en stock. More Info

The A2503S3-O is a dual-band three-element omnidirectional antenna for use in 802.11n MIMO applications. Housed in a compact, low-profile radome, the antenna can be mounted on a mast, cabinet, or ceiling. It can also be mounted to a flush surface via the four mounting holes. Each of the three MIMO antenna elements is connected to the radio via a low loss, plenum-rated coax pigtail. The radiation patterns are uniform and symmetrical, providing high-level 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 for 2.4-2.5 GHz band and 5.15 to 5.85 GHz band applications.

Características y Beneficios



MIMO (Multi Input, Multi Output)
