BAE SYSTEMS ADH SERIES

GENERAL DESCRIPTION


TUNABLE HORIZONTAL DIPOLE ANTENNAS - ADH SERIES, GROUND VERSION

photo BAE Systems ADH Series The ADH antenna is a horizontally polarized antenna fitted with an adaptive tuing mechanism.

Available in two frequency bands (2-30 MHz and 3-30 MHz), the antenna is mounted on a 9 metre high tubular mast.

A hinged mast base is incorporated enabling ease of installation and access to the adaptive tuning mechanism.

Up to 8 MHz the antenna is predominantly omnidirectional becoming bidirectional when operated between 8-30 MHz.

The ADH series operates in conjunction with a fully automatic remote control unit.
