The antenna is nothing more than a simple 2.4 metre square loop drawing pinned to the internal brick wall of the spare bedroom. Yep, thats right, the inside wall of the spare bedroom - ideal for flat dwellers, hotel rooms or whinging neighbours, The loop has a simple switched inductance at the top of the square loop and uses a simple coaxial stub to tune the antenna. An additional variable capacitor placed across the feedpoint can be used to fine tune the resonance of the antenna, by Andy G0FTD

Excellent Quad Antenna projects for 40 20 17 12 10 and 6 meters band in this pdf file project by Pfeiffer Maltese. The Pfeiffer Maltese Quad Antenna System takes on the structural challenges of traditional cubical quad antennas using a linear loading approach to reduce size while preserving performance. Andrew Pfeiffer created the pattern, which resembles a Maltese cross and enhances endurance in tough conditions. The system progresses through numerous configurations, from the 4-spreader Maltese Quad to the 16-spreader Maltese Quadruple-Cross, greatly lowering antenna size while retaining efficiency over several bands, including 12 to 40 metres.

Build your mobile antenna which outperforms Hustler by 10db and ATAS-100 by 18db. From 80 to 10m. The HB9ABX mobile HF antenna, designed for 10 to 80 meters, was developed by Felix Meyer and outperforms commercial antennas like HUSTLER and YAESU ATAS-100/120 in field tests. Made from fiberglass rods and enamelled copper wire, it includes a loading coil with adjustable taps for tuning across bands. Installation requires solid grounding, and adjustments are made via whip length and coil settings. An antenna tuner ensures optimal SWR. Users must handle fiberglass with care due to health risks. This design proved highly effective in South America and Europe.
