DK7ZB Moxon Antennas

DK7ZB provides detailed construction plans for Moxon antennas utilizing tapered aluminum tubing, specifically outlining dimensions for 50 MHz, 28 MHz, 24 MHz, and 21 MHz bands. The resource emphasizes maintaining specific taper lengths for optimal performance and describes a tuning method involving symmetrical element shifts. It also addresses stacking considerations, noting that two Moxons can be stacked 1m apart with a 90° rotation to avoid severe detuning, unlike co-planar mounting.

Performance figures for the 50-MHz Moxon include a gain of 4.1 dBd and a front-to-back ratio of 30 dB. The construction utilizes copper fittings for element connections, with a recommendation to varnish edges against corrosion. The page features images of built antennas by DK8UH and VK2QO, illustrating practical implementations for the 6-meter and 10-meter bands, respectively.
