FlySpark 3.3G Long-Range FPV VTX Series | 4.5W & 10W Analog Video Transmitter Modules | 3060MHz–3840MHz

Key facts

At a glance

The FlySpark 3.3G Long-Range FPV VTX Series is a pair of analog FPV video transmitter modules for the 3.3 GHz band: the VTX-F8 (64 channels, 3060–3500 MHz, up to 4.5 W) and the VTX-F14 (80 channels, 3060–3840 MHz, up to 10 W). Both take DC 7–36 V input, provide a 5 V output, use an SMA antenna connector and support IRC control, OSD parameter adjustment and PIT mode. They are intended for long-range FPV, fixed-wing and UAV video-link integration where the operator holds the required spectrum authorisation.

Use cases

• Long-range analog FPV video links
• Fixed-wing FPV and UAV platforms
• Surveillance and inspection UAV video payloads
• Alternative video band to 1.2G, 1.7G, 2.2G and 5.8G systems
• Drone R&D and field evaluation

Standards & references

• ITU Radio Regulations — International allocation table for the 3060–3840 MHz range the VTX-F8 and VTX-F14 transmit in.
• India National Frequency Allocation Plan 2022 (DoT, WPC Wing) — States that a WPC licence is required before using spectrum in India unless exempted; 3060–3840 MHz is not in the NFAP-2022 list of licence-exempt bands.
• WPC licensing (Department of Telecommunications, Saral Sanchar portal) — Portal for WPC licences, including import and experimental licences, that apply to high-power transmitters such as these 4.5 W and 10 W modules.

Mission overview

FlySpark 3.3G Long-Range FPV VTX Series | 4.5W & 10W Analog Video Transmitter Modules

The FlySpark 3.3G Long-Range FPV VTX Series is a high-power analog FPV video transmitter family designed for FPV drones, long-range UAVs, fixed-wing aircraft, surveillance drones, inspection platforms, drone R&D systems and professional analog video-link integration. Operating in the 3.3GHz frequency class, this series provides high-power video transmission options for users who require an alternative FPV video band beyond common 1.2G, 1.7G, 2.2G and 5.8G systems.

The series includes two variants: 3.3G 4.5W VTX-F8 and 3.3G 10W VTX-F14. Both models support IRC control protocol, OSD parameter adjustment, PIT Mode, SMA antenna interface, DC 7V–36V input and DC 5V output. The VTX-F8 provides 64-channel coverage from 3060MHz to 3500MHz with up to 4.5W output, while the VTX-F14 provides 80-channel coverage from 3060MHz to 3840MHz with up to 10W output.
