Loop on the ground hf antenna

WebFigure 1: Classic rain-gutter-height loop, elevated on standoffs (stylized for emphasis) To find out, I challenged the rain-gutter loop with EZNEC antenna modeling software. This required best-case and worst-caswe models to encompass most house variables: (1) two loop heights, (2) two house types and (3) several bands. WebTransmitting loop antennas intended for optimal coverage of the HF spectrum from 3.5 MHz to 30 MHz are best segregated into at least 2 distinct loop sizes. A nominal 0.9m diameter loop for covering all the upper HF bands from 20m through to 10m (and perhaps also tunable down to 30m depending on capacitor min/max ratio), and a 2m diameter …
