COMPACtenna
ATTICAPTUR40

HF 40-Meter Attic Antenna

Enjoy 40-meter performance without the space requirements of a full-size dipole. The COMPACtenna AttiCapture HF 40-Meter Attic Antenna delivers impressive HF performance in a compact, attic-friendly design, making it an excellent solution for HOA-restricted properties, limited-space installations, and operators who want to stay active on one of amateur radio’s most reliable bands.

Designed specifically for the 40-meter band, AttiCapture 40 combines innovative engineering concepts, including an optimized shortened half-wave dipole, V-feed configuration, spiral loop interaction, and mass-capacitance techniques. The result is a compact antenna system that maximizes performance while occupying only about an 11 ft. x 2 ft. footprint in the attic.

Despite its small size, the AttiCapture 40 is built for serious operation. The antenna supports up to 200 watts SSB voice and 100 watts on other modes under normal operating conditions, giving operators reliable contacts through changing propagation conditions and across the sunspot cycle.

Proudly manufactured in the USA, each antenna is skillfully hand-crafted, precision-machined, and individually tested and tuned before shipment to help ensure consistent performance and quality.
