Finding enough space for HF antennas is becoming increasingly difficult. Small backyards, limited roof access, and portable operation often force radio amateurs to compromise between antenna size and performance.
This compactopen sleeve dipole antenna solves that problem rather elegantly
The open sleeve dipole antenna combines operation on both the 40 and 20 meter amateur bands while remaining considerably shorter than a conventional full-size dipole. Despite the reduced dimensions, performance remains surprisingly good, making it an attractive solution for portable stations, field operation, temporary installations, and restricted urban environments.
