Frequently asked questions
What is an RFID traffic antenna used for?
An RFID traffic antenna such as the IDTS-RA12550 is used for vehicle management and access control, reading tags on cars and trucks as they pass. Its narrow 30 degree horizontal beam gives lane-by-lane detection, which reduces cross-reading between adjacent lanes at gates and parking entries in India.
What is the gain of this long range vehicle RFID antenna?
The IDTS-RA12550 delivers 12 plus or minus 0.5 dBi gain with a 30 degree horizontal and 70 degree vertical beam, giving long-range vehicle tag detection from a gantry or pole. It is circularly polarised, handles up to 50 W and uses an N-type connector for low-loss cable runs.
Which frequency does the IDTS-RA12550 traffic antenna support?
The IDTS-RA12550 traffic antenna supports 920-925 MHz and 902-928 MHz. Confirm the band variant that matches your UHF RFID reader before ordering, since India's licence-free UHF RFID band notified by WPC is 865-867 MHz. Our team in India can advise on the right antenna for your reader.
Can this vehicle RFID antenna be installed outdoors?
Yes. The IDTS-RA12550 RFID traffic antenna is IP65 rated for outdoor gantry and pole installation, with pole mounting for 100 to 300 mm poles and DC ground lightning protection. Its long-strip 550 x 230 mm body suits toll lanes, factory gates and society entries in India.
