SIRIO WY400-6N 6 400-470MHz Element Beam Antenna

New 6-element UHF yagi antenna conceived by using an innovative feed system studied and applied to have highly symmetrical radiation pattern in both planes.

The WY400-6N is 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 easy access.

To increase the antenna gain these can easily be stacked or bayed array
