Core Performance Advantages

  •  ‌Exclusive Low-band Spectrum‌: Operating at the 3.3GHz dedicated frequency band, it completely bypasses the crowded 2.4GHz/5.8GHz civilian spectrum, eliminating co-channel interference from WiFi, Bluetooth and other consumer electronics. It maintains rock-solid signal output even in multi-drone cluster operation environments.
  •  Outstanding Penetration Performance‌: The low-frequency signal features natural obstacle-bypassing properties, which performs far better than high-frequency VTX in penetrating dense vegetation, urban building walls and complex terrain, drastically reducing unexpected signal blackouts during flight.
  •  ‌Long-range Transmission Capability‌: Supports 8 customizable switchable channels, with adjustable power levels covering 25mW to 4W. Its maximum line-of-sight transmission range exceeds 20km, which is 4 times the effective range of a standard 5.8G 1W VTX.
  •  ‌Stable FM Modulation‌: Adopts FM frequency modulation technology paired with a built-in active cooling module, ensuring zero frame drop and no signal packet loss even under long-duration high-power working conditions.

    Our racing team switched to 3.3GHz after 5.8GHz congestion became unbearable during multi-drone events. The MATEN 5W VTX PRO gives us clean video even with 12 drones in the air simultaneously the 3.3GHz band is practically empty compared to crowded 5.8GHz spectrum. The 48-channel range and IRC Tramp control let us remotely adjust frequencies mid-race without grounding drones. CNC aluminum housing takes the occasional hard landing without failure. We've deployed 40 units across three racing circuits. Zero interference issues. This is the new standard for professional FPV racing.

    We integrated the 5W 3.3GHz VTX into our long-endurance inspection UAVs for power line and pipeline patrol. The 7-36V wide voltage input allows seamless integration across different airframes. What sold us was the IRC remote adjustment our ground crew can switch channels and power levels on the fly without recovering the aircraft. In field testing, we maintained stable video at 8-10km over industrial zones with heavy 5.8GHz interference. The 64-channel coverage gives us plenty of clean spectrum even when running multiple UAVs on the same mission. This VTX is now standard on all our 90+ minute flight platforms.

    We provide aerial coverage for global motorsport events where 5.8GHz and 2.4GHz bands are completely saturated with telemetry, timing, and broadcaster equipment. The 3.3GHz 3W VTX with 16 channels (3170-3470MHz) operates in a clean spectrum window that nothing else touches. We've deployed these on 8 camera drones simultaneously across a 5km race circuit crystal clear video with sub-100ms latency. The 25mW-3W adjustable power lets us dial down for pit area close ups and crank up for long tracking shots. For international broadcasting where reliability is non negotiable, 3.3GHz is the only choice.

    We operate a fleet of 20+ agricultural spraying drones across 10,000 acres of farmland. The 5.8GHz band gave us constant dropouts near power lines and irrigation infrastructure. Switching to 3.3GHz 5W VTX solved everything. The 3170-3470MHz range provides excellent penetration through light foliage and around farm structures. Smart Audio and IRC Tramp support let our ground team manage all VTXs from a single GCS. With 15 channels, we can run 5-6 drones simultaneously without interference. The signal stability means our pilots can focus on spraying accuracy instead of worrying about video link. This is the backbone of our entire operation now.

    We manage border surveillance projects across three continents, and frequency compliance used to be a nightmare each region had different restrictions. The KH-3350T's 3170-3470MHz range aligns with unlicensed ISM bands across EU, Asia, and the Americas, dramatically reducing our legal overhead. The 25mW micropower mode lets us operate legally in urban environments and indoor facilities like warehouse robotics and museum security without worrying about regulatory fines. The 7-36V wide-voltage input means we can drop this VTX into anything from 12V drone batteries to 24V industrial rails to 36V solar powered remote stations without additional voltage conversion. We've deployed over 200 units across 12 countries with zero compliance issues. For cross-border industrial IoT and surveillance networks, this is the gold standard.

FAQ

 

What is a 3.3GHz Video Transmitter and what are its advantages?

3.3GHz Video Transmitter is an analog video transmission module operating in the 3.3GHz band, primarily used for FPV drones, remote surveillance, industrial inspection, and other long-range, high-penetration video transmission applications. Key advantages include:

Clean spectrum: The 3.3GHz band is far less congested than the crowded 5.8GHz and 2.4GHz bands, providing extremely low interference even with multiple drones operating simultaneously.

Superior penetration: Outperforms 5.8GHz in obstructed environments such as forests and urban areas.

Low latency: End-to-end delay <20ms, ideal for real-time FPV control.

What antenna should I choose?

You must use an antenna specifically designed for the 3.3GHz band with the correct connector type (SMA, MMCX, or MCX). Never use 2.4GHz or 5.8GHz antennas – this will severely degrade performance and may damage the VTX. Common antenna types include:

Dipole: Omni-directional, suitable for everyday flying.

RHCP (Circular Polarized): Omni-directional, good multipath rejection.

Patch / Yagi: Directional, ideal for ultra-long range.

How to optimize for best transmission performance?

Antenna is crucial: Use a high-gain directional antenna (e.g., patch or Yagi) on the ground receiver to significantly improve range.

Maintain clear line-of-sight: Keep the path between TX and RX as unobstructed as possible.

Choose a clean frequency: The 3.3GHz band is relatively clean, but still avoid other signal sources on the same band.

Ensure proper cooling: High-power transmission generates heat; ensure good ventilation.

Check antenna connection: A loose or damaged SMA connector is the most common source of impedance mismatch, causing power to reflect back into the VTX as heat.

Why does the signal degrade or drop out after some flight time?

Possible causes include:

Overheat protection: When VTX temperature exceeds 100°C, power is reduced incrementally until temperature drops below 95°C.

Loose antenna: Vibration may cause the antenna connection to loosen.

Frequency interference: Entering an area with interference on the same band.

Unstable voltage: Battery voltage drop may cause abnormal VTX operation.

Are 3.3GHz VTX antennas larger than 5.8GHz ones?

  1. Yes, they are typically larger. The physical size of an antenna is proportional to the wavelength. Since 3.3GHz has a longer wavelength than 5.8GHz, the same type of antenna (e.g., a dipole) will be larger. This should be considered when selecting antennas and planning your drone's layout.
