Aerialacts - MaxiMoxon is aerialacts trade name for its line of compact, monoband, two-element, uni-directional parasitic beam antenna arrays utilizing Yagi-style aluminum elements. MaxiMoxon models are available for the 20, 17, 15, 12 and 10 meter amateur radio bands.

EH antenna power lost considerations - Out of Balance Current or Longitudinal Mode Current in the Coaxial Cable causes radiation from the coax. But how large a proportion of the total power is radiated or lost from this Current?

EH antennas and CFA antenna - Many antennas function because of common mode currents, rather than working in spite of them. Two popular examples are CFA and EH antennas. Another recent example, appearing in Antennex's compact antenna articles, is a thick stub "vertical" with no counterpoise.

G5RV multi-band antenna - Multi-band centre-fed antenna capable of very efficient operation on all HF bands, specifically designed with dimensions which allow it to be installed in gardens and other open spaces which accommodate a reasonably-straight run of 31.1m (102 ft) for the flat-top standard model.
