A: FT1573 is the smallest variant with 20mm × 16mm × 5.4mm dimensions.

A: SK-VTX11 is the highest-power variant with up to 10W or 10000mW output.

A: FT1573 is suitable for compact racing and lightweight FPV builds, while higher-power models are better for long-range builds.

A: VTX-F1-72, VTX-F2-72, SK-VTX12 and VTX-F18 support 72-channel coverage from 4867MHz to 6100MHz.

A: SK-VTX11 supports 80 channels from 4867MHz to 6100MHz.

A: FT1573 supports 5362MHz–5945MHz.

A: The 72CH variants support 4867MHz–6100MHz.

A: Yes. All listed variants support PIT Mode.

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

A: FT1573 supports DC 7V–28V. The other listed variants support DC 7V–36V.

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

A: FT1573 uses an IPEX antenna interface.

A: VTX-F1-72 and VTX-F2-72 use MMCX antenna interfaces.

A: SK-VTX12, VTX-F18 and SK-VTX11 use SMA antenna interfaces.

A: VTX-F2-72 uses 30.5mm × 30.5mm spacing with M3 threaded holes.

A: These variants use 20mm × 20mm spacing with M2 threaded or mounting holes.

A: Yes. The higher-power variants are suitable for long-range analog FPV video transmission when used with proper antennas, receiver system, cooling and legal RF permissions.

A: Yes. The 5.8G 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: The supported input voltage depends on the selected variant. Use clean power and verify voltage compatibility before installation.

A: No. Do not power a 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 FT1573 400mW for the most compact builds.

A: Choose VTX-F1-72 1.6W or VTX-F2-72 3W depending on mounting and output requirement.

A: Choose SK-VTX12 4W or VTX-F18 5W for high-power long-range builds.

A: Choose SK-VTX11 10W if maximum listed RF output is required.

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.
