Military HF Mobile Whip Antennas



AT Military Vehicle HF Antenna The various AT Military HF whips antennas are designed to be used with an Automatic Antenna Tuning Unit (ATU), such as the AT T-1.
They are suitable for mounting on any horizontal, flat surface.
They can be supplied with any hole pattern base.
They are extremely rugged, and meet MIL-STD 810 and Australian Defence Standard DEF-STAN 00-35.
The standard version is 3 metres high, and designed for mobile operation. Extra elements are available as an option so that it can be transformed into a 6m whip for stationary use—a guy kit is included. The AT T-1 tuner should be used with this configuration.
A Near Vertical Incidence Skywave (NVIS) kit is included, for enhanced close-in operation.
Other variants are available in 2.4m and 3.0m lengths, with high-impact shock mounts or more cost-effective springs.
The shock mount variant can be flexed to 90° from the vertical with no damage caused to the base unit and whip antenna.
Carbon-fibre and aluminium elements are available.
