• EFHW Anntenna 40-10 for QRP - The author discusses their endeavour to create a compact, robust resonant antenna for QRP operations due to strong winds in their area. Primarily designed for 40m and 20m bands, the article offers adaptability for different bands. The author hints at future projects, including an extended 8010 EFHW variant, promising a lighter yet efficient design.

• Full size 80m End Fed Half Wave Antenna - The author reflects on expanding their antenna for 80m coverage during lockdown. They extend the End Fed Half Wave (EFHW) using a Spiderbeam pole and "cheating" by dog-legging across their garden. Despite challenges, they achieve coverage for multiple bands with minimal cost. Practical Wireless features EFHW antennas, including a pre-made 20m EFHW extended for 40m.

• Enhancing Performance with W8JK/MOXON Antenna Variant - F5NPV introduces a variant of the W8JK antenna design, employing the MOXON principle. With extended monopoles, it outperforms the Open-Folded W8JK, yielding a 1dbd gain improvement, enhanced performance on 30m and 10m bands, bi-directionality, and lower side attenuation. The design's focus on higher radiation impedance results in increased antenna efficiency and reduced losses. Despite these improvements, the bill of materials remains unchanged.
