Boost Your DX: The Ultimate 30m/40m Dual-Band Delta Loop antenna
This dual‑band delta loop uses a 40 m base loop and clever tuning tails to switch seamlessly between 30 and 40 metres. It is aimed at DXers seeking low‑angle radiation and strong performance from a moderate footprint. The article includes full dimensions, feed‑point details and measured results to help you replicate the antenna safely at home.
Ultimate DIY Tri-Band 80M, 40M and 30M Trapped Delta Loop Antenna
This trapped delta loop covers 80, 40 and 30 metres from a single triangular wire structure using carefully tuned traps. It is ideal for operators who want three popular HF bands but only one main support structure. The guide explains trap construction, loop dimensions, matching arrangements and on‑air performance including DX and regional contacts.
Small Magnetic Loop: A Guide to the Foldable 40m–17m Stealth Antenna
This foldable magnetic loop based on the PA0WIT design offers efficient operation from 40 to 17 metres in extremely limited spaces. It emphasizes very low noise and tight footprint, making it perfect for high‑RFI apartments. The article dives into Faraday loop dimensions, capacitor choices, measured SWR, and tips for safely handling high voltages on the capacitor.
Super Mini Loop Antenna: A Compact Multi-Band HF Performer
Inspired by W8JI’s design, this super mini loop is a full‑wave HF loop compressed into a small form factor while retaining good multiband performance. The write‑up covers loop geometry, feed methods, band coverage and practical optimization hints. It is well suited to experimental builders wanting an efficient yet unobtrusive HF antenna.
