Description
To achieve a 25dBi gain, these antennas utilize a significantly longer boom with a high number of precisely spaced director elements. This physical length allows the antenna to “capture” and focus RF energy into an incredibly narrow beamwidth, making it capable of reaching towers that are 20km+ away under clear line-of-sight conditions. While most standard Yagis top out at 18dBi, the 25dBi variant is the choice for users in “deep fringe” areas where any other antenna would fail to register a signal.
The dual-band design is particularly effective for mobile signal repeaters; it can simultaneously boost voice calls (900 MHz) and high-speed data (1800 MHz). Built with passivated aluminum and UV-resistant components, these antennas are rated for all-weather outdoor operation and typically feature an N-Type Female connector for low-loss integration with thick LMR-400 cabling.
Key Technical Advantages
-
Extreme Amplification: The 25dBi gain is among the highest available for passive directional antennas, extending the effective range significantly further than standard models.
-
Dual-Band Versatility: Seamlessly supports both 900MHz and 1800MHz bands, covering GSM, 3G, and 4G LTE services on a single cable run.
-
High Directivity: The narrow radiation pattern effectively rejects off-axis noise and interference, providing a “cleaner” signal for data-heavy applications.
-
Ruggedized Construction: Features a high-quality aluminum structure designed to withstand high wind loads and corrosive environments.
-
Lightning Protection: Often includes direct DC grounding to protect indoor equipment from atmospheric electrical surges.
