Wideband Maritime Log Periodic Dipole Array


The LPDA-A0134 is a directional log-periodic dipole array primarily designed for EW monitoring in maritime applications. It covers the 100 - 1000 MHz frequency band with a typical gain of greater than 6 dBi. Based on the more tactical LPDA’s that are on offer the LPDA-A0134 features an upgraded mechanical and environmental design to ruggedize the antenna for marine use.
