FPV Video Transmitters (VTX) Sourcing from China | 1.2G/3.3G/5.8G | Up to 5W Output Power | SourcingProChina
Product Overview
SourcingProChina is a sourcing agent based in China, specializing in connecting overseas buyers with vetted factories producing FPV video transmitters (VTX) across 1.2GHz, 3.3GHz, and 4.9-5.8GHz frequency bands, with output power up to 5W. Rather than manufacturing directly, we act as your on-the-ground sourcing partner — handling factory communication, sample coordination, quality inspection, and shipment consolidation for FPV racing, industrial inspection, and other commercial drone applications.
Through our supplier network, buyers can access VTX units featuring MMCX antenna connectors, SmartAudio or IRC Tramp control protocols, and support for both NTSC and PAL video systems. Multiple mounting patterns (20×20mm and 30.5×30.5mm) are available to match most drone frame specifications — we help you confirm exact compatibility with the sourced factory before placing a bulk order.
Technical Specifications

FAQ
Q1: What frequency bands can SourcingProChina help me source?
We work with factories producing VTX in 1.2GHz (1080-1360MHz), 3.3GHz (3200-3500MHz), and 4.9-5.8GHz (4990-5945MHz) bands. As your sourcing agent, we confirm the exact frequency certification for your destination market before ordering.
Q2: What is the maximum output power available?
The 5.8GHz 5W model offers the highest output power in our current supplier catalog. 3.3GHz and 1.2GHz models are also available up to 5W. We recommend verifying local RF power regulations with us before bulk import.
Q3: What control protocols are supported, and can you confirm FC compatibility?
5.8GHz models typically support SmartAudio; 3.3GHz and 1.2GHz models typically support IRC Tramp. As part of our sourcing service, we request factory confirmation of protocol compatibility with your specific flight controller model prior to order confirmation.
Q4: What antenna connector type do these VTX use?
Factory-sourced units use MMCX connectors as standard. We can inquire about SMA/U.FL alternatives if required for your project — please specify in your inquiry.
Q5: Can these VTX be mounted on standard drone frames?
Yes. 5.8GHz models generally use 20×20mm mounting; 3.3GHz and 1.2GHz models generally use 30.5×30.5mm mounting. We recommend requesting a sample or CAD drawing through us before finalizing your frame design.
Q6: What is the input voltage range?
Most sourced models support 7-36V (2-8S) or 7-28V (2-6S) depending on the specific model. We verify actual tested voltage range against the factory's QC report for each batch.
