Wideband Foldable LPDA Antenna


The LPDA-A0150 is medium-gain wideband directional LPDA antenna and covers the frequency band from 20 MHz to 100 MHz. This antenna has foldable elements which makes the antenna easy to stow and deploy. There are no loose parts and no tools required to deploy the antenna. This makes the antenna ideal for tactical applications as well as for use in harsh environments and installations where there is limited space for operators to manoeuvre. All antenna elements are permanently attached to the boom, to prevent any parts from becoming lost in the field.
