Introduction
Standard Background and Technology Evolution
With the upgrade of civil aviation communications from traditional VHF to LTE ground-to-air data link, the MH/T 9010 series of standards has built a complete ATG technology system. As a special specification for airborne antennas, this part fills the gap in the standardization of domestic aviation broadband communication antennas.
Core parameter requirements
| Indicator items | Technical requirements | Test basis |
|---|---|---|
| Frequency support | Must comply with MH/T 9010.1 frequency band division | Network planning and design |
| Standing wave ratio (VSWR) | ≤2.0 | RTCA DO-160G |
| Power tolerance | ＞Terminal maximum transmit power | Laboratory load test |
| Environmental adaptability | -55℃~85℃ continuous operation | RTCA DO-160G Section 4/5 |
Key design elements
1. Streamlined structure design
The standard requires that the antenna shape must comply with the aerodynamic drag reduction principle. Typical cases include:
- Knife-shaped antenna commonly used in business jets: size ≤300×150×50mm
- Shark fin antenna for transport aircraft: integrated multi-band design
2. Materials and reliability
Must pass the RTCA DO-160G Chapter 26 flame retardant test. It is recommended to use:
- Shell: glass fiber reinforced PEEK
- Sealing material: fluororubber
Implementation suggestions
1. Key points for installation acceptance
- The antenna spacing must meet the isolation requirement of 3λ or above
- TNC or 7/16 DIN type is recommended for the RF interface
- VSWR measurement under flight status is required
2. Airworthiness compliance method
It is recommended to prepare a safety analysis report in accordance with Article 1309 of CCAR-25-R4, with the following highlights:
- Lightning protection compliance (DO-160 Section 22)
- Electromagnetic compatibility (DO-160 Section 20/21)
