Product features 

Electrical performance: The general-purpose antenna suitable for UHF band RFID applications has the characteristics of high gain, low standing wave, etc. It has the dual advantages of the far-distance reading distance of the linearly polarized antenna and the non-directionality of the circularly polarized antenna.

Mechanical properties: Beautiful and compact appearance, waterproof design with waterproof ring and silicone, shell with reinforced design, suitable for all kinds of harsh environments.


Application

The SM-T0258 can be easily used in RFID applications such as access control, warehousing, logistics, and retail in the UHF band.。


Install

The SM-T0258  can be mounted on the steel frame structure or pillar by its own bracket or user-fitted bracket, and connected to the reader through the coaxial cable. The antenna can be installed horizontally or vertically, depending on the mounting orientation of the bracket. After installation, the tilt angle of the antenna can be adjusted according to the actual situation.

The antenna mount is an option and the customer can choose as needed.
