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.

例如, 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 (超高頻) 樂團, 範圍從 300 兆赫至 3 百萬赫. It should include a video transmitter to connect to your camera and a receiver to connect to your monitor. 也, 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, 無人機, and other sources.

UHF video transmitters vary in their frequency range, 輸出功率, 調製方案, 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) 從 30 到 300 megahertz (兆赫). The wavelength range of VHF is from ten meters to one meter.

UHF Video Transmitter – Detailed Overview

Product Definition
一個 UHF video transmitter is a device that wirelessly transmits video signals over the Ultra High Frequency (超高頻) 樂團. 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.

• 頻率範圍: Commonly 300 兆赫至 3 百萬赫, often 500–900 MHz for practical applications.
• 訊號類型: Can be either 模擬 (simpler, low-latency CVBS) 或者 digital (compressed, high-quality HDMI/SDI using H.264/H.265 or COFDM modulation).

---

典型應用

• Drone/UAV video transmission: Real-time video feedback to ground stations.
• 安全和監控: Wireless CCTV transmission without long cables.
• Live event broadcasting: Wireless feed for concerts, 運動的, or TV production.
• Professional or military monitoring: 低延遲, 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 (模擬)
• 傳輸距離: Varies with power output and environment
• 延遲: 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
