[Jeri] Builds A Magnetic Loop Antenna. The controller provides "UNI" and "BI" modes. Any configurations have to fit in my 100ft long by 40ft wide garden and my aim was to try out several different configurations to see if I could improve my signal on 160m and 80m without compromising the performance on the HF bands. Sure enough, many approaches, both old and new, exist to help an 80 or 75m dipole present a decent SWR across the entire 80m band. These are manual tuners designed to tune small loop antennas, and are. The motivation for the long wire loop admittedly was to garner high performance, omnidirectional coverage on the low frequency bands of 160 through 40 meters, in response to our inexorable slide down the backside of the current sunspot cycle. The first requirement for a magnetic loop antenna is that the antenna must be resonant.
