DIY Antennas, QRP, SDR & Ham Radio Projects from VU3DXR
Master the 80m–10m bands with the classic W3DZZ trapped dipole. This guide explores the technical design, trap construction, and real-world SWR performance of this legendary multi-band antenna. Perfect for hams seeking a compact, high-performance HF solution without a complex tuner
This 80M Trapped dipole antenna is the work of Nadisha 4S7NR, modified by YC0HLE which results are matched at a frequency of 3,845 MHz. This design will be resonant at a frequency of around 3,250MHz to 3,850MHz. Coil inductance = 67.83 µH, made of email wire diameter = 1 mm, diameter of the cocker = […]
