ALFA Network AYA-4G-18 18dBi Outdoor Directional 4G LTE Yagi Antenna

The AYA-4G-18 is a directional antenna designed for operation across the 1710–2700 MHz frequency range, with a specified gain of 18 dBi. Its directional radiation pattern concentrates coverage within defined horizontal and vertical beamwidths of 40° and 36°, helping focus the antenna toward the intended signal path rather than distributing energy equally in all directions. The antenna supports both vertical and horizontal polarization, providing installation flexibility where either orientation is required. A VSWR below 1.5 and 50-ohm impedance define its RF interface characteristics, while the maximum input power of 100 W establishes the stated power handling limit for the antenna.

For connection to compatible RF equipment, the antenna is fitted with an N Male connector and includes a 30 cm RG58 cable. It is designed for pole mounting and supports installation on poles with diameters from 30 to 50 mm, giving clear mechanical requirements for deployment. The enclosure measures approximately 80 mm in diameter and 450 mm in length, with a listed weight of 800 g. Its operating temperature range extends from −40 °C to 70 °C, supporting use across a broad range of environmental conditions. A rated wind velocity of 60 m/s further defines the mechanical conditions the antenna is designed to withstand when properly installed on a suitable pole.
