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 …

WebI assume when you say SkyLoop you are referring to a horizontal loop, like a delta, square, rectangle, circle, or stop sign or similar. I have both a 160 Meter and 80 Meter horizontal loop at 400 feet above ground level average height. Both are square. The 160 Meter loop is fed with Open Wire Line and the 80 Meter antenna uses 450 Ohm Ladder line. Web4 de jan. de 2024 · Loop-on-Ground, the simplest Receive-Antenna you will ever Build, and it Works.

WebDescription: The model 8020CA Magnetic Loop Antenna by DoxyTronics is. a lightweight, ultra-portable, trail friendly HF antenna. which covers 3-15mhz including the 80/75m/60m/40m/30m/20m. Amateur Radio bands. Handles 25w PEP SSB, 15w Digital. modes. Main features: Ultra portable – can be easily stored inside a small. Web24 de mar. de 2024 · Horizontal HF antennas … benefit from nearby ground gain. At a height of about λ/2, the nearby ground reflection of a horizontal HF antenna will start to be constructive at interesting take-off angles for long- distance ionospheric contacts. This will provide a net gain over the antenna in free-space.
