For the applications discussed here, these are the recommended oscilloscopes.

These application notes cover the “how to” in using our products. Some deal with the technical aspects of the various measuring devices and methods. They are written to be understood by new hams, yet provide the theoretical background when needed. All the application notes are in PDF format. These notes are copyright protected but may be down loaded as long they are for individual use only and their entire contents is shown.

Magnetic Loop Antenna

PreciseLOOP antennas.  Technical description, maximizing gain, radiation patterns, loop current, SWR plots, comparisons to the dipole antenna and internet discussions. In makes an excellent adjunct to those using any loop antenna or to those considering buying one.
