Specifications
| Parameter | Value | |-----------|-------| | Model | CF-RA1201 | | Gain | 12dBi | | Frequency | 865-868MHz (EU) / 902-928MHz (US) | | Polarization | Linear/Circular optional | | Reading Distance | 0-15 meters | | Radiation Angle | H: 40° / V: 40° | | Connector | N-Female | | Wind Resistance | 60 m/s | | IP Rating | IP67 | | Size | 445×445×40mm |
Why Choose 12dBi High-Gain Antenna?
1. Longer Reading Distance
Combined with CF-815 reader, achieves 15+ meters stable reading.
2. Narrower Beam
40° beam angle means more precise detection zone, reducing cross-lane misreads.
3. Outdoor Durability
IP67 rating + 60m/s wind resistance for all weather conditions.
Installation Tips
Height Selection
- Align antenna center with tag height
- Recommended 0.8-1.2m from ground
Angle Adjustment
- Vertical mounting, facing incoming traffic
- Fine-tune tilt for optimal reading
Linear vs Circular Polarization
| Feature | Linear | Circular | |---------|--------|----------| | Distance | Longer | Shorter | | Direction Sensitive | High | Low | | Recommended | Fixed tag orientation | Random orientation |
Linear polarization recommended for GoKart as tags are fixed on car front.
