Sirio WY 108-3N 108-137 MHz 200Watts 7dBi Air Band 3 Elements Yagi Antenna

Description

Sirio WY 108-3N 108-137 MHz 200Watts 7dBi Air Band 3 Elements Yagi Antenna
Base station antenna conceived by using an innovative feed system studied and applied to have highly symmetrical radiation pattern in both planes (E and H). It’s completely computer designed to get high performances of gain and front-to-back in the working band. All aluminium parts are protected by anodized treatment, hardware are of Stainless steel or zinc plated steel, mounting bracket is of extruded aluminium for the best strength and the connector is placed in rear position for an easily access. To increase the antenna gain please install it in vertical stacked array.
Features:
Base station antenna, Directional
Wide band, High-gain
Highly symmetrical radiation pattern in both planes (E and H)
Protection from static discharges DC-ground
Made of anodized aluminium alloy
Stacked and bayed array for more gain
Optional: tilting bracket for +-20°
