FlySpark 4G / 4.8G Long-Range FPV VTX Series | 4.5W & 10W Analog Video Transmitter Modules | 3700MHz–4800MHz

A: It is a high-power analog FPV video transmitter series for drones and UAVs, available in 4.5W and 10W output-power variants.

A: The available variants are 4.8G 4.5W VTX-F19 and 4G 10W VTX-F20.

A: The starting price is ₹23,940 for the 4.8G 4.5W VTX-F19 variant.

A: The price of the 4.8G 4.5W VTX-F19 is ₹23,940.

A: The price of the 4G 10W VTX-F20 is ₹32,800.

A: VTX-F19 supports 4020MHz–4800MHz.

A: VTX-F20 supports 3700MHz–4330MHz.

A: The 4G 10W VTX-F20 is the highest-power variant with up to 10000mW RF output.

A: The VTX-F20 supports 64 channels, while VTX-F19 supports 40 channels.

A: VTX-F19 supports PIT Mode, 25mW, 200mW, 1600mW and 4500mW.

A: VTX-F20 supports PIT Mode, 25mW, 200mW, 4000mW and 10000mW.

A: Yes. Both listed variants support PIT Mode.

A: Yes. Both variants support IRC control protocol and OSD parameter adjustment.

A: Both variants support DC 7V–36V power supply input.

A: Yes. Both listed variants provide DC 5V output.

A: Both variants use SMA antenna interface.

A: VTX-F19 uses 20mm × 20mm spacing with M2 threaded holes.

A: VTX-F20 uses 20mm × 20mm spacing with M2 mounting holes.

A: VTX-F19 dimensions are 48.5mm × 35mm × 18.2mm.

A: VTX-F20 dimensions are 60mm × 36mm × 22.8mm, excluding SMA head.

A: Yes. These 4G / 4.8G VTX modules are suitable for long-range analog FPV video transmission when used with proper antennas, receiver system, cooling and legal RF permissions.

A: Yes. The 4G / 4.8G VTX series is suitable for fixed-wing FPV platforms and long-range UAV builds where analog video transmission is required.

A: No. This is an analog FPV video transmitter series.

A: It supports DC 7V–36V input, but the exact connection depends on the drone power system. Use clean power and verify voltage compatibility before installation.

A: No. Do not power a high-power VTX without a properly connected antenna or dummy load, as it may damage the RF output stage.

A: Higher output power can improve link margin, but actual range depends on antenna gain, receiver sensitivity, line of sight, RF noise, installation quality, cable loss, power supply stability and legal operating limits.

A: Choose VTX-F19 4.5W if you need 4020MHz–4800MHz coverage with 40 channels and 4.5W output.

A: Choose VTX-F20 10W if you need the highest output power and 3700MHz–4330MHz 64-channel coverage.

A: Users must follow WPC/DoT/local spectrum regulations, drone operation rules, site permissions and RF safety practices. High-power RF transmission should only be operated where legally permitted.

A: Warranty support is 1 Year for manufacturing defects under approved integration and normal operating conditions. Damage from reverse polarity, over-voltage, overheating, antenna mismatch, powering without antenna, crash, water ingress, unauthorized modification or illegal operation may not be covered.
