GRA-AT330T(C) Motorized HF Screwdriver Antenna

The Gabil GRA-AT330T Motorized HF Screwdriver Antenna is a versatile, precision-tunable antenna designed for amateur radio operators who want reliable multi-band HF performance without the need to manually adjust the antenna. Covering 3.5–50 MHz, it provides operation from 80 metres through to 6 metres when used with the appropriate whip configuration.

At the heart of the GRA-AT330T is its motorised loading coil, allowing the antenna to be tuned quickly and accurately from the supplied controller. Rather than relying on the radio to control the antenna, the operator has direct control over the coil position, making it easy to fine-tune for the best possible SWR and signal performance.

The controller also features 10 memory presets, allowing frequently used frequency positions to be stored and recalled at the touch of a button. This makes changing between bands considerably quicker, particularly during mobile operation, portable activities and POTA (Parks on the Air) activations.

Built with demanding outdoor use in mind, the GRA-AT330T features an IP68-rated waterproof construction, providing excellent protection against dust and water. Its rugged design makes it well suited to vehicle installations as well as portable and field-based operating.

The GRA-AT330T version features a UHF (PL-259) base connection, providing compatibility with a wide range of suitable antenna mounts and mobile installations.
