two way wireless video data audio link module wireless video transmitter receiver

1420Mhz -1530Mhz frequency range drone video data link has 110Mhz frequency range, so it supports frequeny hopping (FHSS) at 11 ponits if set bandwidth 10Mb.

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

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

	Version 1	Version 2
Frequency Range	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

The 1420-1530 MHz frequency range for drone video data links is part of the L-band, known for its balance between range and data throughput, making it suitable for long-distance communication. Here’s a detailed breakdown:

Key Characteristics:

Frequency Range Attributes:
- Longer Range: Lower frequencies (compared to 2.4 GHz/5.8 GHz) enable communication over greater distances, ideal for Beyond Visual Line of Sight (BVLOS) operations.
- Better Obstacle Penetration: Effective in urban or vegetated environments where signals must pass through buildings or foliage.
Applications:
- Commercial Drones: Used in infrastructure inspection, agriculture, and delivery services requiring reliable long-range links.
- Military/Government: Secure, robust communication for surveillance or reconnaissance.
- Public Safety: Emergency response drones in disaster zones where traditional networks fail.
Technical Trade-offs:
- Lower Data Rates: Compared to higher bands, but modern compression (e.g., H.265) allows HD video transmission.
- Interference Mitigation: Techniques like frequency hopping or directional antennas may be employed to enhance reliability.
Challenges:
- Regulatory Compliance: Operators must ensure transmissions avoid protected frequencies (e.g., 1400-1427 MHz). In practice, systems often use 1427-1530 MHz to prevent overlap.
- Spectrum Crowding: Increased use of L-band for aviation/satellite may require coordination.
Conclusion:
- The 1420-1530 MHz band is a strategic choice for drones needing long-range, 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.
