The Siemens 6GT2812-1AA08 is a UHF RFID antenna from the SIMATIC RF600 family, designated RF662A. It covers the 865 to 928 MHz frequency band with circular polarization and a gain of 7 dBi, making it suited for global UHF RFID deployments across ETSI and FCC regions. It connects via an RP-TNC male plug and is designed for use with SIMATIC RF600 readers. The housing is Pocan material in Ti gray, and mounting uses 4× M4 screws on a VESA 100 pattern, or an optional articulated bracket via the antenna mounting kit.
A maximum VSWR of 1.5 indicates good impedance matching across the band — reflected power stays low, so the radiated energy goes into the tag, not back into the cable. That translates to consistent read range without hot spots. The 50 Ω impedance matches standard UHF coaxial infrastructure (LMR-400, RG-213, etc.) without an external matching pad. Radiation pattern is 56° horizontal, 58° vertical — a moderately narrow beam that concentrates energy downrange rather than spilling into adjacent zones. Useful for dock-door portals or conveyor chokepoints where you want to read only the tags passing through the aperture.
The product status is Active per Siemens lifecycle data. This is a current-production antenna, not a phase-out or NRND line.
