1420Mhz -1530Mhz frequency range drone video data link module — 1420Módulo de link de dados de vídeo drone com faixa de frequência Mhz -1530Mhz

This is a special customized version of the Vcan1681 drone wireless video and data module.

	Versão 1	Versão 2
Alcance de frequência	806-826Mhz 1428~1468Mhz 2401.5~2481.5Mhz	1420~1530MHz
Frequency Hopping Range	Three frequency bands between 800Mhz, 1.4Ghz and 2.4Ghz.*	1420-1530Mhz (now PA and antenna support)

* Frequency hopping at 800Mhz, 1.4Ghz and 2.4Ghz needs the power amplifier and antenna to support.

Models with K in them such as CX6602K support 1420-1530Mhz

1420Mhz -1530Mhz frequency range drone video data link module with cables

o1420-1530 Faixa de frequência MHz for drone video data links is part of theBanda L, known for its balance between range and data throughput, making it suitable for long-distance communication. Aqui está uma análise detalhada:

Enable frequency hopping in the configuration.

Características principais:

Frequency Range Attributes:
- Longer Range: Frequências mais baixas (compared to 2.4 GHz/5.8 GHz) enable communication over greater distances, ideal paraBeyond Visual Line of Sight (BVLOS) operações.
- Better Obstacle Penetration: Effective in urban or vegetated environments where signals must pass through buildings or foliage.
Aplicações:
- Commercial Drones: Used in infrastructure inspection, agricultura, and delivery services requiring reliable long-range links.
- Military/Government: Seguro, robust communication for surveillance or reconnaissance.
- Segurança Pública: Emergency response drones in disaster zones where traditional networks fail.
Technical Trade-offs:
- Lower Data Rates: Compared to higher bands, but modern compression (por exemplo, H.265) allows HD video transmission.
- Mitigação de interferência: Techniques like frequency hopping or directional antennas may be employed to enhance reliability.
Desafios:
- Conformidade Regulatória: Operators must ensure transmissions avoid protected frequencies (por exemplo, 1400-1427 MHz). Na prática, systems often use1427-1530 MHz to prevent overlap.
- Spectrum Crowding: Increased use of L-band for aviation/satellite may require coordination.
Conclusão:
- o1420-1530 MHz band is a strategic choice for drones needinglongo alcance, reliable video links, especially in regulated or challenging environments. Compliance with radio astronomy protections (avoiding ≤1427 MHz) and proper licensing are essential for legal operation. This range is favored in sectors prioritizing reach and penetration over ultra-high data rates.
