The WR-155 AIS antenna is a vertical, ground-plane-free monopole antenna with 3,5dBi gain. Specifically recommended for mobile marine stations in the AIS band.

Its low vertical radiation lobe (12°) and omnidirectional pattern provide good performance. 

Robustly constructed from stainless materials, it is weather-resistant.

Its small dimensions and low weight make installation easier.
