| Index | Verification method | |
|---|---|---|
| 3.7.1 Antenna characteristics | Polarization | Vertical polarization using information or measurement |
| Power handling | Radiating 15 W average power using information or measurement | |
| Bandwidth | Least 20 MHz at 1,030 MHz and 1,090 MHz using information or measurement | |
| 3.7.2 Antenna VSWR/RF transmission line loss | VSWR | VSWR(≤2:1) measurement at 1,020/1,030/1,040/1,080/1,090/1,100 MHz |
| Insertion line loss | Loss(≤3 dB) measurement at 1,030/1,090 MHz | |
| 3.7.3 Antenna pattern | Omni-directional in the horizontal plane, vertical beam width of at least ±30° from horizontal plane 0° antenna elevation pattern to verify that the total antenna system gain, including system losses, at the receiver input is greater than −4 dBi for ⭘⭘ %, −6 dBi for ⭘⭘ %, −8.5 dBi for ⭘⭘ % of the coverage volume → So, ≥－4 dBi: ⭘⭘ %, ≥－6 dBi: ⭘⭘ %, ≥－8.5 dBi: ⭘⭘ % @ ±30° from horizontal plane | |
| 3.7.4 Isolation | Isolation(≥⭘⭘ dB) measurement between the antenna transmission lines | |
