Скачать или смотреть Antennas Part III: DIY HF Antenna for Ionospheric Propagation - DC to Daylight

In this application-based video, Derek makes use of the general knowledge of dipole antennas that he's gained to create a simple two-element antenna that provides some directivity. By introducing a reflector near the driven element, he can manipulate and direct the RF energy in one direction.

He'll also talk a bit about the ionosphere, the evolution of our antenna from dipole to the Moxon design, and cover the build process of his DIY antenna. Lastly, he takes the new rig out to the park for a test run to try and contact some folks in different countries!
