Enjoy 40-meter performance without the space requirements of a full-size dipole. The COMPACtenna AttiCapture HF 40-Meter Attic Antenna is engineered to deliver impressive HF operating capability from 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. The AttiCapture also makes a great antenna for POTA, SOTA, and other portable operations, and can be placed on a floor, or hung on a wall, or even set on a picnic table.

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 operating. The antenna supports up to 200 watts SSB voice and 100 watts on other modes under normal operating conditions, allowing operators to enjoy reliable contacts throughout 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.

Antenna Placement:

ATTIC/ROOM: May be placed on a floor which is above ground, or hung on a wall above ground

POTA: May be placed on picnic tables (non-conductive type)
