TV Anetenna Outdoor Digital Tv
Indoor ground wave Yagi Antenna is equipped with strong magnetic base and sucker, which can be firmly attached to smooth surfaces such as glass and metal without complicated tools and cumbersome steps, making installation easy and simple. Outdoor models are equipped with professional brackets, which support multi-angle flexible adjustment, accurately aim at the best signal receiving direction, and ensure signal stability without attenuation. In terms of technical performance, the ground wave Yagi digital tv antenna is particularly outstanding. Its frequency range covers two key frequency bands: 174-230MHz and 470-862MHz, which completely covers the frequency range of TV broadcasting and does not miss any wonderful programs. The standard input impedance of 75 ohms is perfectly matched with common TV signal Transmission lines, effectively reducing signal transmission loss; Ultra-low voltage standing wave ratio (VSWR) of 1.5 ensures efficient and stable signal transmission, and bid farewell to the picture jam and blur; The gain design of up to 28dBi greatly enhances the signal receiving ability, and can receive stably even in the weak signal area; With the maximum input power of 50W, it can cope with different signal environments calmly, bringing users a smooth viewing experience. In the physical structure design, the digital TV Antenna of ground wave Yagi is full of humanized ingenuity. The standard cable length of 3 meters is enough to cope with most conventional installation scenarios, and it also supports flexible customization. Whether it is exquisite layout in narrow corners or long-distance connection in open spaces, it can be easily adapted, providing unlimited possibilities for installation. The F/LEC connector is adopted to break down the equipment barrier with strong versatility, and it is easily compatible with various signal receiving devices on the market, plug and play, without worrying about adaptation problems. The overall size of the antenna is only 330*300mm, which is compact and does not occupy land. Whether it is concealed indoor installation or flexible outdoor installation, it can be skillfully integrated into the environment; The ultra-light weight of 0.5kg greatly reduces the installation burden, and a single person can easily complete the installation and handling, and the operation is convenient and pressure-free. We deeply cultivate the industry, provide one-stop OEM and ODM professional customization services, and cooperate deeply throughout the whole process to help enterprises create differentiated products. From the aesthetic design of product appearance, to the rigorous screening of materials and technology, to the precise adjustment of core performance parameters, every link supports personalized customization. Whether you want to create a unique and eye-catching brand visual identity or meet the special technical requirements in complex scenes, our experienced R&D and design team will work closely with you to tailor exclusive product solutions based on advanced technology and mature technology. With the full chain service capability, we are committed to breaking through the homogenization competition for corporate customers, meeting the diversified market demand in an all-round way, and empowering brand value upgrade. 1. How to adjust the receiving direction of Outdoor Antenna? The outdoor model is equipped with a professional adjustable bracket, which supports 360 horizontal adjustment and 90 vertical adjustment. The bracket has an angle scale. Just aim at the direction of the local signal tower and tighten the fixing screw. It is recommended to cooperate with the field strength meter to fine-tune it to the best signal value. 2. What is the function of 75 ohm input impedance? 75Ω is the standard TV signal impedance, which is perfectly matched with common transmission lines such as SYWV-75-5. The measured signal transmission loss rate is less than 3%, which improves the efficiency by 40% compared with the traditional antenna, and the picture quality can be kept clear by long-distance wiring. 3. What is the concept of voltage standing wave ratio (VSWR)1.5? VSWR reflects the degree of signal reflection, and 1.5:1 is an ultra-low value (the ideal value is 1:1), which can suppress the interference of signal reflection, and the smear rate of the measured picture is less than 0.5%, and snowflakes and jams can also be avoided in multipath signal environment.
