How to choose a high-quality base station antenna?
2025/03/01
When selecting a high-quality base station antenna, several key factors need to be considered to ensure optimal performance and reliability. Here are some guidelines for making an informed choice:
Antenna Type: Choose the appropriate antenna type based on the wireless environment and equipment requirements. For instance, in urban areas with dense base stations and small individual coverage areas, antennas with a horizontal half-power beam width of around 60 to 65 degrees are often selected.
Gain and Directionality: Antenna gain determines the signal strength and coverage area. Higher gain usually means better directionality and more concentrated energy. Select medium-gain antennas (around 15dBi) for urban areas to balance coverage and interference control. For rural areas, high-gain antennas are preferable to achieve wider coverage.
Polarization: In urban areas with limited installation space, dual-polarized antennas are commonly used. In more open rural areas, vertically polarized antennas may offer better performance.
Frequency and Size: The frequency range supported by the wireless communication network determines the antenna size. Higher frequencies allow for smaller antennas due to shorter wavelengths.
Bandwidth: The antenna should maintain good performance across the specified frequency range. A wide bandwidth is beneficial for multi-band solutions.
Impedance Matching: Ensure the antenna's input impedance matches the transmission line for maximum power transfer. Most modern antennas require a 50-ohm impedance.
Material and Durability: Choose high-quality materials to enhance the antenna's durability and stability. ABS material, for example, can extend the product's lifespan and maintain antenna performance.
By carefully considering these factors, you can select a high-quality base station antenna that meets your specific needs and ensures optimal network performance.
