UHF Digital Long-Range Video Transmitter UHF Video Transmitter

One-way and two-way are the two types of UHF video transmitters, which are categorized based on project needs.

For example, an ordinary video photograph camera only needs to transmit the video from the transmitter to the receiver; but drones often not only need wireless transmission from the camera to a remote monitor, and the control instructions issued by the operator at the receiver joystick need to be uploaded to the drone. This is a two-way transmission.

A UHF video transmitter is a device that can send video signals wirelessly over the ultra-high frequency (UHF) band, which ranges from 300 MHz to 3 GHz. It should include a video transmitter to connect to your camera and a receiver to connect to your monitor. Also, support transmitter antenna and receiver to become on a full set of UHF video transmitter systems.

We use UHF video transmitters for broadcasting TV shows and transmitting video from cameras, drones, and other sources.

UHF video transmitters vary in their frequency range, output power, modulation scheme, data rate, and antenna type..

Perhaps you’ve heard of VHF or very high frequency. It is the frequency range of radio frequency electromagnetic waves (radio waves) from 30 to 300 megahertz (MHz). The wavelength range of VHF is from ten meters to one meter.

UHF Video Transmitter: Digital vs Analog Selection Guide

Feature / Criteria	Analog Video Transmitter	Digital Video Transmitter
Signal Type	Composite Video (CVBS/AV)	HDMI, SDI, H.264/H.265
Frequency Band	UHF (commonly 500–900 MHz)	UHF (500–900 MHz)
Video Quality	Lower resolution, prone to noise	High resolution, stable, less interference
Latency	Very low (1–5 ms)	Low (30–50 ms, depends on codec)
Distance	Short to medium	Short to long (depending on power & environment)
Typical Use	DIY FPV, basic CCTV	Professional drones, live broadcasting, surveillance
Pros	Simple, low cost, minimal setup	Stable, supports multi-channel, longer range, high quality
Cons	Susceptible to interference, lower quality	More complex, slightly higher cost, may introduce small delay

UHF Video Transmitter – Detailed Overview

Product Definition
A UHF video transmitter is a device that wirelessly transmits video signals over the Ultra High Frequency (UHF) band. It can convert video from sources such as HDMI, SDI, or analog CVBS/AV into radio signals, which are then received by a compatible UHF video receiver.

• Frequency range: Commonly 300 MHz to 3 GHz, often 500–900 MHz for practical applications.
• Signal type: Can be either analog (simpler, low-latency CVBS) or digital (compressed, high-quality HDMI/SDI using H.264/H.265 or COFDM modulation).

---

Typical Applications

• Drone/UAV video transmission: Real-time video feedback to ground stations.
• Security and surveillance: Wireless CCTV transmission without long cables.
• Live event broadcasting: Wireless feed for concerts, sports, or TV production.
• Professional or military monitoring: Low-latency, robust video transmission for reconnaissance or tactical operations.

---

Customer Considerations
When selecting a UHF video transmitter, customers often focus on:

• Video input type: HDMI/SDI (digital) vs CVBS/AV (analog)
• Transmission distance: Varies with power output and environment
• Latency: Critical for drones or real-time control applications
• Signal stability and interference resistance: Digital COFDM modulation offers better robustness in complex environments
• Regulatory compliance: Must adhere to local frequency usage laws
