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.

على سبيل المثال, 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 (التردد فوق العالي) فرقة, الذي يتراوح من 300 ميغاهيرتز إلى 3 غيغاهرتز. It should include a video transmitter to connect to your camera and a receiver to connect to your monitor. أيضًا, 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, طائرات بدون طيار, and other sources.

UHF video transmitters vary in their frequency range, طاقة الإخراج, مخطط التعديل, معدل البيانات, 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) من 30 ل 300 megahertz (ميغاهيرتز). The wavelength range of VHF is from ten meters to one meter.

UHF Video Transmitter – Detailed Overview

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

• نطاق التردد: Commonly 300 ميغاهيرتز إلى 3 غيغاهرتز, often 500–900 MHz for practical applications.
• نوع الإشارة: Can be either التناظرية (simpler, low-latency CVBS) أو digital (compressed, high-quality HDMI/SDI using H.264/H.265 or COFDM modulation).

---

التطبيقات النموذجية

• Drone/UAV video transmission: Real-time video feedback to ground stations.
• الأمن والمراقبة: Wireless CCTV transmission without long cables.
• Live event broadcasting: Wireless feed for concerts, رياضة, or TV production.
• Professional or military monitoring: الكمون المنخفض, robust video transmission for reconnaissance or tactical operations.

---

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

• Video input type: هدمي/سدي (digital) vs CVBS/AV (التناظرية)
• مسافة الإرسال: Varies with power output and environment
• كمون: Critical for drones or real-time control applications
• Signal stability and interference resistance: Digital COFDM modulation offers better robustness in complex environments
• الامتثال التنظيمي: Must adhere to local frequency usage laws
