In the field of digital television, DTMB antennas and ordinary antennas are two common receiving devices. They have certain differences in principle, function, and application scenarios. This article will compare DTMB antennas and normal antennas.
Ordinary antenna is a device that receives radio wave signals, mainly used to receive analog TV signals or digital TV signals. It works by using the electromagnetic waves captured by the antenna, converting them into electrical signals, and then transmitting them to a TV or digital TV receiver box through a cable, and finally displaying them on the screen.
DTMB antenna is a kind of antenna specially used to receive digital TV signals, it adopts DTMB technology, which is the digital TV broadcasting technology specified in the Chinese national standard GB 20600-2006. The DTMB antenna realizes the reception and development of high-definition digital TV programs by receiving terrestrial digital TV signals and converting them into digital signals, and then transmitting them to digital TV receiving equipment.
Wide range of application: ordinary antennas are suitable for receiving analog TV signals and some earlier digital TV signals.
Poor signal stability: Due to the influence of terrain, building occlusion and other factors, the signal stability received by ordinary antennas is poor, and the picture may be blurry or the signal may be interrupted.
Low cost: The production and installation cost of ordinary antennas is relatively low, which is suitable for general home users.
Professional digital signal reception: DTMB antenna is specially designed to receive digital TV signals, and can receive high-definition digital TV programs.
Strong signal stability: DTMB antenna adopts advanced digital signal processing technology, which can effectively resist interference, ensure stable signal, and clear and smooth picture.
Relatively high cost: Due to the more advanced technology used in the DTMB antenna, the production and installation costs are relatively high, which is suitable for users who pursue high-definition image quality.
Ordinary antennas are suitable for some areas or scenarios where users do not have high requirements for digital TV signals, such as some rural areas or old residential areas.
DTMB antennas are suitable for scenarios with high requirements for digital TV signals, such as urban residential areas, commercial areas, office areas and other places, especially for users who pursue high-definition picture quality.
To sum up, there are certain differences between DTMB antennas and ordinary antennas in terms of principles, functions, characteristics and applicable scenarios. Ordinary antennas are suitable for general users, with low cost but poor signal stability; The DTMB antenna is suitable for users with high requirements for digital TV signals, with strong signal stability but high cost. When choosing an antenna, you should choose according to your own needs and budget to meet the demand for digital TV signals. Hopefully, this article will be helpful to readers to better understand the difference between a DTMB antenna and a normal antenna.
