GMB8UB application field and working principle

The GMB8UB is a two-bay wideband antenna system built for applications in the industrial, public safety, and military communication arenas. It’s designed to continuously cover the Frequency bands between 137 and 512 MHz, offering the user the highest levels of performance within the wideband antenna marketplace. GMB8UB antennas can be used as a base or portable antenna, mobile antenna, or distributed antenna system.

The GMB8UB wideband antenna system is an effective tool for many applications due to its superior gain, low VSWR, superior radiation patterns, and power handling capability. Its low physical profile and aerodynamic design also make the GMB8UB an ideal choice for fleet communications, base station operations, and distributed antenna systems. It comes with the option of dual polarization and frequency selective designs.

Components of GMB8UB

The GMB8UB consists of two wideband antenna elements, a low noise amplifier (LNA), and a dual polarized power splitter. Each GMB8UB element is designed to cover the Frequency band between 137 and 512 MHz and has a gain of 8-9 dBi. The dual polarized power splitter allows each element to be selectively switched to either Horizontal or Vertical polarization, providing the antenna with a total gain of up to 16-18 dBi.

Working principle

The GMB8UB is designed to provide increased gain and efficiency over comparable wideband antennas. The GMB8UB antenna system operates by using a low noise amplifier (LNA) to amplify the incoming signal. The amplified signal is then split into two polarized signals by the power splitter. The polarized signals are then fed into each of the antenna elements which each produce their own electromagnetic field and radiates the incoming signal in the desired direction.

The antenna elements are designed to provide a high level of directional resolution, isolating different aspects of the incoming signal. This enables the GMB8UB to produce a higher level of gain and signal fidelity than comparable wideband antennas. In addition, the GMB8UB also includes a dual polarization design which enables the antenna system to radiate a signal in both the Horizontal and Vertical plane simultaneously.

Conclusion

The GMB8UB is a two-bay wideband antenna system built for applications in the industrial, public safety, and military communication arenas. It is designed to continuously cover the Frequency bands between 137 and 512 MHz, providing the user with the highest levels of performance within the wideband antenna marketplace. The GMB8UB antenna system operates by using a low noise amplifier and a dual polarized power splitter to amplify the incoming signal and provide increased gain and efficiency. The GMB8UB is an ideal choice for fleet communications, base station operations, and distributed antenna systems.
