Telus Cell Phone Number Block

Vehicle-mounted electronics Telus Cell Phone Number Block In practical applications, the antenna should be made small and concealed. As long as it is a customer, it will be the same. However, the key parameters of the antenna used in the cell phone jammer are carrying power and gain. The car antenna has to withstand the power of 50-100W. There is a necessary condition. The antenna cannot be as thin as a wire, nor can it only be as large as a palm, otherwise the power is enough to burn the antenna itself. If the antenna of the electronic mobile phone jammer is made smaller (reduced in size or height), the gain value of the antenna will be reduced a lot. Take an omnidirectional antenna as an example, the gain value of the frequency below 500MHz is usually 0-3dB, and the frequency is 500MHz. Above, the gain value is 7-8dB.

  • After the antenna is made small, in terms of gain value, the gain value below 500MHz will be reduced to a negative value, generally -5 to -2dB. And above 500MHz, the gain value is only 3-5dB.
  • The gain value of the antenna directly affects the range of the electronic Telus Cell Phone Number Block signal.
  • For every 3 dB difference in the gain value, the power difference is doubled.
  • For example, for a 100W module exporting RF power, a conventional omnidirectional antenna with a gain value of 8dB is used.

It can be transmitted normally and the signal coverage is also suitable

If it is changed to a small-sized antenna with a gain value of 5dB, the gain value of the antenna will be reduced by 3dB, and the power will be doubled. That is, the module with the original output power of 100W will immediately It becomes only 50W effective transmit power. This is a waste of RF power consumption and power consumption.

Antennas are crucial components of cell phone jammers, especially in vehicle-mounted applications where practicality and efficiency are paramount. While customers may prefer concealed antennas for aesthetic reasons, there are key parameters, such as carrying power and gain, that must be carefully considered in the antenna design.

One of the primary challenges in designing antennas for vehicle-mounted cell phone jammers is finding a balance between size and performance. Since these antennas need to withstand relatively high power outputs of 50-100W, they cannot be too thin or small. Otherwise, they risk burning out due to the excessive power load. On the other hand, overly large antennas may not be practical for vehicle installations due to space constraints.

The gain of the antenna is another critical factor that directly influences the range and effectiveness of the cell phone jammer. Antennas with higher gain values can transmit signals over longer distances and provide better coverage. However, reducing the size of the antenna typically results in a decrease in gain.

For example, with omnidirectional antennas, the gain value is typically lower for frequencies below 500MHz, ranging from 0 to 3dB. As the frequency increases beyond 500MHz, the gain value typically rises to 7-8dB. When antennas are made smaller, especially in terms of height, the gain values decrease significantly. Antennas with reduced size may have negative gain values below 500MHz, typically ranging from -5 to -2dB, and only modest gain values of 3-5dB above 500MHz.

The reduction in gain directly impacts the effective transmit power of the cell phone jammer. For every 3dB decrease in gain, the effective transmit power is halved. For instance, if a 100W RF power module is paired with an antenna with an 8dB gain, it can transmit effectively over a certain range. However, if the antenna is replaced with a smaller one with a 5dB gain, the effective transmit power drops to only 50W, leading to reduced signal coverage and potentially inefficiencies in RF power consumption.

Therefore, in the design of vehicle-mounted cell phone jammers, antenna considerations play a crucial role in optimizing performance while ensuring practicality and efficiency in real-world applications. Balancing power requirements, gain values, and antenna size is essential to achieve optimal signal coverage and jamming effectiveness.
