It covers the full 865 to 928 MHz band, so it works across ETSI (Europe) and FCC (North America) frequency allocations without swapping hardware. The housing is Pocan with an IP65 seal, meaning it handles washdown and dust out here in the grease — fine for conveyor lines, warehouse gates, or outdoor yard entry points where moisture and grime are routine. You can set this antenna for linear vertical, linear horizontal, circular, or combined polarization. That matters because tag orientation on a moving pallet or carton is unpredictable — circular polarization catches tags at any twist angle, while linear gives you extra range when the tag alignment is known. The horizontal beam is 90°, vertical is 77°, so coverage is a broad cone rather than a tight pencil beam. Gain runs 3.5 dB for both linear and circular radiation, which is typical for a medium-gain panel antenna in this class. ## Mounting and mechanical integration Mounts with four M4 screws on a VESA 100 pattern — the same hole spacing as many industrial monitors and panel PCs, so you can use standard brackets. There's also an articulated bracket option via the antenna mounting kit if you need to aim it. The RP-TNC male connector is at the antenna end; antenna cables from 1 to 40 m are available separately. No integrated cable whip — the wire length is listed as 0 m, meaning you supply the coax run. ## Environmental toughness Rated for -25 to +75 °C during operation, and -40 to +85 °C during storage or transport. Shock tested to 300 m/s² and vibration to 100 m/s². Silicon-free construction. Status is active per Siemens lifecycle tracking. No end-of-life notice or successor part number is recorded.","metaTitle":"Siemens 6GT2812-2GB08 SIMATIC RF680A RFID Antenna, 865-928 M","metaDescription":"Siemens 6GT2812-2GB08 SIMATIC RF680A antenna for RF600 systems.
