Problems solved by technology
[0005] However, the indoor devices in the CPE system are low-cost devices that do not provide grounding components, so the antenna feeder SPD cannot play the role of lightning protection
If the indoor equipment is equipped with grounding components or independent grounding equipment, the material cost and construction cost are too high, even greatly exceeding the indoor equipment to be protected, and cannot be widely used

The embodiment of the invention discloses signal transmission device, system and method, which are used for realizing lightning protection on the premise of ensuring communication and low cost. The antenna device comprises a first antenna, a second antenna and an insulator connector, the first antenna and the second antenna are arranged in an isolated manner through the insulator connector. The signal transmission direction of the first antenna points to the second antenna; and / or the signal transmission direction of the second antenna points to the first antenna. If the first equipment is arranged outdoors, and when the first equipment is hit by lightning, lightning is transmitted to the first antenna, since the first antenna and the second antenna are isolated through the insulator connector and are not in direct contact, the first antenna does not conduct thunder to the second antenna, so that the thunder cannot be conducted to the second equipment, and the second equipment is protected from being struck by the thunder on the premise that the first equipment and the second equipment can communicate with each other.
Description
technical field [0001] The present application relates to the field of antennas, and in particular to a signal transmission device, system and method. Background technique [0002] In a wireless network, the customer premise equipment (CPE) system can receive wireless signals or 4G signals from devices such as wireless routers, wireless access points, or wireless base stations, and convert them into wireless-fidelity (Wi-Fi) signals. ) signals or long term evolution (long term evolution, LTE) signals for use by users. The CPE system can be applied in places where optical fibers are not popular, such as rural areas, towns, or countries or regions with relatively backward communication equipment. [0003] The CPE system includes outdoor antennas, cables, and indoor devices. The outdoor antennas are connected to indoor devices through cables. Outdoor antennas are used to receive wireless signals, and transmit wireless signals to indoor devices through cables, such as 4G signa...
