| 1 | Frequency-band coverage | 15% | Confirm the antenna is designed and specified for the required operating band, not merely described as “wideband.” | Datasheet frequency range, measured response across the band, and the test conditions used. |
| 2 | Gain and radiation pattern | 14% | Compare gain and beam shape at the frequencies and in the installation conditions relevant to the project. | Gain in dBi, horizontal and vertical beamwidth, and radiation-pattern plots with frequency and polarization identified. |
| 3 | Impedance match | 12% | Check matching performance across the required band and against the system’s feed-line impedance. | VSWR or return-loss plots, nominal impedance, connector details, and measurement setup. Acceptance limits should be set for the application. |
| 4 | Polarization and cross-polarization | 12% | Verify polarization type, orientation, and cross-polarization performance for the intended link. | Polarization specification and co-/cross-polarized pattern data measured over the operating band. |
| 5 | Power handling and electrical design | 10% | Ensure the stated power rating and feed arrangement match the transmitter, duty cycle, and system configuration. | Rated input power, connector and cable specifications, grounding details, and any stated derating conditions. |
| 6 | Mechanical and environmental suitability | 10% | Check dimensions, mounting, materials, and environmental ratings against the deployment location. | Mechanical drawings, operating-temperature range, stated IP rating where applicable, and supporting environmental test reports. |
| 7 | Measurement and quality controls | 8% | Assess whether test methods, instrument calibration, traceability, and production inspection are documented. | Sample inspection records, calibration records, test procedures, and relevant quality-management documentation such as ISO 9001 certification if claimed. |
| 8 | Customization and engineering support | 7% | Determine whether the supplier can support the required connector, mounting, radome, cable, or pattern changes. | Written design-change scope, prototype process, technical response time, and revision-control practices. |
| 9 | Production capacity and lead-time reliability | 6% | Check that quoted capacity and delivery schedules are supported by the supplier’s actual production and sourcing plan. | Current lead-time quotation, production-capacity statement, order-change policy, and delivery performance data where available. |
| 10 | Documentation, compliance, and after-sales support | 6% | Review documentation completeness, applicable market requirements, warranty terms, and support arrangements. | Datasheets, drawings, declarations or test reports relevant to the destination market, warranty conditions, and replacement or repair process. |
| Total Suggested Weight | 100% | Score each supplier using the same requirements and evidence standard. |
