Description
The 14dBi LPDA Antenna represents the peak of directional wideband performance for consumer and commercial signal enhancement. With a higher gain than standard 9dBi or 12dBi models, this antenna utilizes a longer boom and precisely calculated dipole elements to provide exceptional reach. It is specifically optimized for Sub-6 GHz 5G frequencies, including the critical C-band spectrum, while maintaining full backward compatibility with all global 4G LTE and legacy 3G bands.
The physical construction is designed for permanent, high-exposure outdoor mounting. It features a heavy-duty ABS radome or a powder-coated aluminum alloy frame that can withstand extreme weather and wind speeds of up to 200 km/h. The high front-to-back ratio ensures that the antenna focuses exclusively on the target cell tower while rejecting unwanted noise and interference. Most professional models come equipped with an N-Female connector, ensuring a robust, low-loss junction for high-performance RF cable assemblies.
Key Technical Advantages
-
Future-Proof 5G Coverage: Extends range up to 3800+ MHz to support the latest 5G mid-band frequencies (N77/N78), ensuring compatibility with the fastest modern data networks.
-
Maximum 14dBi Signal Boost: Provides the highest gain in the LPDA family, essential for locations several miles from the nearest tower where signal penetration is minimal.
-
