About the product
The AP21799 is a collinear base antenna designed to operate from 405 to 440 MHz, ideal for fixed UHF radio communication systems.
Its folded dipole and low main-lobe radiation pattern provide wide signal coverage and excellent performance, especially where reliable communications are required.
Made with an aluminum structure and high-quality coaxial cable, the antenna ensures durability, weather resistance and electrical stability, making it the ideal choice for repeater stations and industrial or urban environments.
