Ultra 1600mW VTX: 1.6W Long-Range Video Transmitter

Still pushing your analog video feed through a wheezing 600mW unit and wondering why your FPV goggles show pure static behind a single hedge? The Ultra 1600mW VTX delivers 1.6W of RF output power across 4.9GHz to 5.8GHz to punch clean through dense obstacles and bando concrete. Backed by Unmanned Tech’s 10 years of experience in the manufacturing and delivery of commercial FPV systems, this long-range video transmitter runs standard IRC Tramp telemetry, integrates seamlessly with your flight controller UART and Betaflight OSD, and accepts direct 7V-36V input from 2S–8S LiPo battery packs without cooking your delicate electronics.

Key Highlights

• 1.6W Long-Range Output: Blast through signal interference with up to 1600mW of RF power across 64 channels.
• Two-Layer Thermal Board: Split BEC and RF mainboard layout shields your video feed from electrical noise while onboard thermal protection prevents instant meltdowns.
• Betaflight & OSD Integration: Full IRC Tramp protocol support allows instant channel, band, and power switching straight from your radio transmitter or OSD.

Why You Want It

Because failsafing video behind a line of damp British trees is a tragic way to lose an expensive carbon fibre frame. The Ultra 1.6W VTX gives your long-range cruiser the penetration it needs without forcing you to endure fiddly button presses in the mud. The integrated microphone streams live motor audio directly to your goggles so you can hear prop wash and throttle response in real time, while the standard 30.5x30.5mm mounting pattern drops cleanly into your main flight stack.

Specifications

• RF Output Power: 25mW / 200mW / 400mW / 800mW / 1600mW / Pit Mode

FAQ

How do I set up the Ultra 1600mW VTX without burning it out on the bench?

Always connect a quality 5.8GHz antenna before applying power. While the Ultra 1600mW features onboard thermal protection, radiating 1.6W of RF power produces serious heat without flight airflow; keep the VTX in Pit Mode or 25mW in Betaflight while bench-testing to avoid triggering thermal throttling or letting out the magic smoke.

What’s in the Box*

• 1× Ultra 1.6W High-Power 5.8GHz VTX
• 1× Plug-and-play wiring harness
• 1× Linear dipole antenna

Disclaimer

Blasting 1600mW on 5.8GHz in the UK will raise eyebrows at Ofcom unless you hold the appropriate amateur radio license and follow local RF power regulations. Never power this board without an antenna securely mounted unless you enjoy the scent of vaporised silicon.

Still Here?

Stop flying on a fuzzy video link and blaming your PID tune. Drop the Ultra 1600mW into your 30x30 stack, paste the CLI config, and fly long-range with complete video confidence.
