Detailed knowledge of the power splitter

When it comes to power splitters, the average user will be unfamiliar. In wireless monitoring projects, when the wireless bridge needs to use more than two antennas, you need to use the power splitter. Then, what role does the power splitter play in the project? What? What other conditions do you need to use a power splitter? Let's take a look at it with Xiaobian.

The power splitter full power splitter can divide one input signal into two or multiple outputs, and in turn can synthesize multiple signals into one output. In the wireless monitoring system, the wireless bridge uses the power splitter to distribute one signal of the bridge output to multiple antennas.

In the wireless monitoring system, when many customers use multiple transmissions to receive video signals, the receiving end can only use omnidirectional antennas to receive signals if the angle is not enough. The gain of the omnidirectional antenna is small, and the transmission distance is also small. Very close. At this time, the power splitter is used to increase the receiving antenna to increase the receiving angle. In this way, the receiving device can save the engineering equipment cost, and the transmission distance is much farther than the omnidirectional antenna. In this case, using the power splitter can save investment and save costs.

The power splitter has these advantages. Is it necessary to add a power amplifier and an antenna directly in the wireless monitoring project without adding equipment for transmitting or receiving? Of course not. The power splitter can be used within a distance of less than three kilometers. If the power splitter is used in the case of long-distance wireless video transmission, if an output port is not connected to the base station output signal, it must be connected. Matching load (ie load resistance) should not be idling; use the power divider to increase the antenna gain if the distance transmitted is much lower. However, the use of the power splitter still affects the transmission distance. Since the power splitter is used to divide the power, it will definitely affect the transmission distance. Forming a blind spot: After using the power splitter, the network performance will be reduced, and some blind spots will be formed. Increase the amount of maintenance: Using the power splitter for the operation and maintenance work, a faulty node is added invisibly, and the quality of the power splitter directly affects the quality of the network.

In summary, the power splitter should be used under proper environmental conditions, and blind use may cause the entire wireless monitoring system to malfunction. For users who do not understand these factors, you can choose a professional and serviced equipment supplier. Tengyuan Zhituo is such a company. Each product data of the company is obtained after repeated tests for 6 months. The performance of the products is industrial-grade wireless transmission quality, which can fully meet the application of users in various environments.
