Product details

The antenna adopts advanced digital signal receiving technology, just like a keen signal hunter. Its built-in precision high-frequency circuit and efficient signal amplifier work together, which can accurately capture the weak signals sent by radio and television towers or satellites and greatly amplify them. Whether it is a weak signal hidden between high-rise buildings in the city or a broadcast signal from a distance, it is difficult to escape its "capture".

High gain means that it has stronger signal capturing ability-even in areas with weak signal coverage (such as remote floors and multi-wall shielding environment), it can accurately capture long-distance and low-intensity TV signals, and effectively amplify the signals through internal optimization circuits, greatly reducing the problems such as snowflakes and jams, presenting a clear and smooth picture quality effect, which makes you feel as if you are in the recording scene of the program and enjoy the audio-visual experience immersive.

In signal transmission, the standing wave ratio (S.W.R) of the DVB-T/DAB-T1/DAB-T2 Antenna is less than 1.5, which directly determines the transmission efficiency and stability. Low standing wave ratio can minimize the reflection loss of signals in the transmission process, so that energy can be transferred from the antenna to the TV equipment more efficiently, avoiding the problems of picture interruption and sound quality distortion caused by signal loss, ensuring the stability of the whole process from signal reception to output, and providing a solid guarantee for high-quality audio-visual.

The antenna is designed with a wide voltage of 3-5V, which fully meets the general power supply standard. No matter whether it is equipped with USB interface of TV, household power adapter, or using portable power supply in special scenes such as car and outdoor, it can easily realize stable power supply, without purchasing special power supply equipment, completely solve the problem of power compatibility, and make installation and use more flexible and worry-free.

Minimum loss design: The input impedance is 75 ohms, which is optimized for minimum signal loss.

Compatible with a variety of devices: the connection type is F/IEC, and this universal connection method is compatible with a series of devices. Whether it is an old-fashioned TV equipment or a new smart TV, it can be easily connected with this antenna, providing more choices for your viewing experience. RG174 professional communication material is selected for TV Antenna With Megnetic Base matching cable, and with the two core advantages of "high durability" and "low signal loss", a reliable defense line is built for signal transmission.

In terms of durability, RG174 cable sheath has excellent anti-wear and anti-aging properties, and it is not easy to have problems such as skin cracking and core oxidation when facing slight bending and environmental temperature and humidity changes in daily use, and it can still maintain stable performance after long-term use; In terms of signal transmission, its special core structure and shielding design can effectively reduce the attenuation loss of signals in transmission-even through long-distance connection, it can retain the high-definition signals received by the antenna to the greatest extent, avoid the picture jam and sound quality distortion caused by cable problems, and always provide you with lasting and clear signal transmission guarantee.

Car Radio Antenna

Q: What is the function of the standing wave ratio index of the antenna, and does it have a great influence on the use experience?

A: The standing wave ratio (S.W.R) of the antenna is ≤ 1.5, which is the key index to determine the transmission efficiency and stability. Low standing wave ratio can minimize the reflection loss of signals during transmission, so that energy can be transferred from antenna to TV equipment more efficiently. This can effectively avoid the problems of picture interruption and sound quality distortion caused by signal loss, ensure the stability of the whole process from signal reception to output, and provide a solid guarantee for high-quality audio-visual.

Q: What are the advantages and durability of RG174 cable matched with antenna?

A: The antenna cable is made of RG174 professional communication material, which has two core advantages of "high durability" and "low signal loss". In terms of durability, RG174 cable sheath has excellent anti-wear and anti-aging properties, and it is not easy to have problems such as skin cracking and core oxidation in the face of slight bending and environmental temperature and humidity changes in daily use, and it can still maintain stable performance after long-term use.

Q: What is the performance of Q：RG174 cable in signal transmission and what problems can be avoided?

A: In signal transmission, the special core structure and shielding design of RG174 cable can effectively reduce the attenuation loss of signals in transmission. Even through long-distance connection, the high-definition signal received by the antenna can be retained to the greatest extent, avoiding the picture jam and sound quality distortion caused by cable problems, and always providing you with lasting and clear signal transmission guarantee.
