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.

مثلا, 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) باند, which ranges from 300 مگاهرتز به 3 گیگاهرتز. It should include a video transmitter to connect to your camera and a receiver to connect to your monitor. همچنین, 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, هواپیماهای بدون سرنشین, and other sources.

UHF video transmitters vary in their frequency range, توان خروجی, طرح مدولاسیون, نرخ داده, 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) از 30 به 300 مگاهرتز (مگاهرتز). The wavelength range of VHF is from ten meters to one meter.

UHF Video Transmitter – Detailed Overview

Product Definition
آ UHF video transmitter is a device that wirelessly transmits video signals over the Ultra High Frequency (UHF) باند. 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.

• محدوده فرکانس: Commonly 300 مگاهرتز به 3 گیگاهرتز, often 500–900 MHz for practical applications.
• Signal type: Can be either آنالوگ (simpler, low-latency CVBS) یا دیجیتال (compressed, high-quality HDMI/SDI using H.264/H.265 or COFDM modulation).

برنامه های کاربردی معمولی

• 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, ورزش, or TV production.
• Professional or military monitoring: تاخیر کم, 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 (دیجیتال) vs CVBS/AV (آنالوگ)
• فاصله انتقال: Varies with power output and environment
• تأخیر: Critical for drones or real-time control applications
• Signal stability and interference resistance: Digital COFDM modulation offers better robustness in complex environments
• انطباق با مقررات: Must adhere to local frequency usage laws
