Product Introduction
Targeted Frequency Coverage：The GL - SD90 - RH771 is designed for the 144 - 430MHz frequency range. This makes it highly suitable for applications that operate within this specific VHF band, ensuring optimal signal transmission and reception for relevant wireless systems.
Decent Gain for Signal Enhancement：With a gain of 3.5dBi, the antenna can effectively strengthen incoming signals. This gain is useful for extending the communication range and improving the signal quality, enabling better connectivity over a reasonable distance.
Stable Impedance and Low VSWR：It has an impedance of 50Ω and a VSWR of ≤1.5. The stable impedance ensures efficient power transfer between the antenna and connected devices, while the low VSWR reduces signal reflection. This results in a more stable connection and reliable signal transmission.
Vertical Polarization Advantage：The vertical polarization of the GL - SD90 - RH771 helps in minimizing interference from horizontally polarized signals. This is particularly beneficial in environments with electromagnetic clutter, ensuring a more stable communication link.
Durable Construction and Wide - range Operation：Made of steel radome material, the antenna is durable and can withstand various environmental conditions. Steel provides good protection for internal components. With a weight of 0.4 kg and a height of 390mm, it is relatively robust yet still manageable for installation. Its operating temperature range of - 40℃ to 80℃ makes it suitable for use in different climates and environments.
Application scenarios
Amateur Radio Communication：Amateur radio enthusiasts can use the GL - SD90 - RH771 for VHF band communication. Its gain and frequency range allow for better signal reception and transmission, enabling them to connect with other operators over longer distances.
Public Safety Communication：Police, fire departments, and emergency services often rely on VHF frequencies in the 144 - 430MHz range for communication. The GL - SD90 - RH771 can be installed on vehicles or at communication centers to ensure reliable communication during emergencies.
Maritime Communication：Boats and ships use VHF radios for communication with other vessels and coastal stations. The GL - SD90 - RH771 can be mounted on boats to improve the range and clarity of VHF signals, enhancing safety at sea.
Aviation Ground - to - Air Communication：At airports, ground - based communication systems that operate in the 144 - 430MHz range can use the GL - SD90 - RH771. It helps in ensuring accurate and reliable communication between air traffic control and aircraft.
Industrial Wireless Monitoring：Industries that use wireless sensors and devices for equipment monitoring and process control in the 144 - 430MHz band can benefit from the GL - SD90 - RH771. It can be integrated into these systems to improve signal strength and reliability.
