WebbA properly designed and constructed small 1m diameter loop will outperform any antenna type except a tri-bander beam on the 10m/15m/20m bands, and will be within an S-point (6dB) of an optimised mono-band beam mounted at an appropriate height above ground. So where’s the catch; if the small loop is such a good antenna why doesn’t everyone ... WebbThere are also small portable rotators that work from 12 VDC. Medium-duty rotators can handle a single mid-sized HF Yagi or log-periodic for 14 to 30 MHz. By “mid-sized,” I mean a Yagi with a few elements on a 12 to 18 foot boom weighing 50 pounds or less. A small VHF/UHF Yagi can be stacked with the HF beam.
