UHF RFID Integrated Antenna IDTS-RA6133 (6 dBi, IP67)

An IP67 UHF RFID antenna for outdoor and wet locations

The IDTS-RA6133 is meant for reading points exposed to weather or dirt: a parking boom, a yard gate, a loading bay open to monsoon rain or a dusty factory yard. Its white PC+ABS housing is IP67 rated, meaning dust-tight and protected against temporary immersion, and the antenna is rated for -40 °C to +55 °C.

Inside, an F4B high-frequency board with a nickel-plated copper reflector gives 6 dBi gain across 860–960 MHz, a range that includes India's 865–868 MHz band.

Coverage: wide rather than long

With a 106° beam in both planes, one RA6133 covers a broad area in front of it, such as a single entry lane or a dock opening at moderate distance. Circular polarisation with a tight axial ratio of ≤2 dB keeps reads consistent when tags on vehicles, cartons or bins arrive at different angles.

Where the reading point must reach further down a lane, or must not pick up the lane next to it, a narrow-beam, high-gain antenna such as the IDTS-RA12550 traffic antenna is the better choice.

Mounting and cabling

• Pole mounting: fits poles of 40–50 mm diameter, a common size for barrier posts and light frames.
• Connector: a 10 cm RG178 lead at the back ends in an MMCX connector. That short lead suits a reader or reader module mounted right beside the antenna; if the reader sits further away, plan an MMCX adapter and a low-loss extension cable.
• Weight and depth: at 600 g and 52 mm deep it is a sturdier unit than indoor panels, so fix it firmly where passing vehicles or wind cause vibration.

What to order with it

The antenna needs a UHF fixed reader with an external antenna port, plus tags suited to what you are tracking: windscreen labels for cars, on-metal tags for containers and machinery.
