Simple Ham Radio Antennas: Antenna Fundamentals 3 Bandwidth. Post #348

Thanks to Javier Anderson for sharing this classic military training film on antennas. This video is the final segment of an antenna study course produced by the National Film Board of Canada for the Royal Canadian Air Force. This film dates from the mid to late 1950s and contains the basic information necessary to discuss antenna bandwidth. The explanation is clear, uncluttered, and thoroughly understandable. This video could be made part of a basic Amateur Radio License Course. For the latest Amateur Radio news and events, please check out the blog sidebars. These news feeds are updated frequently.

Simple Ham Radio Antennas: Ham Radio General Class Lesson 6.2, Dipoles, Ground-planes, and Random Wires. Post #344

Here is another one of Dave Casler's (KE0OG) excellent, well-paced tutorials on amateur radio antennas. This time, Dave discusses antenna theory and design basic to passing the FCC Amateur Radio General Class License exam. Dave focuses his attention on Ground-Planes, Random Wires, and Dipoles--all of which can deliver plenty of contacts if they are built correctly. While Dave's advice on coaxial cable feedlines is quite good, I feel the use of balanced feeders (450 ohm ladder line or 300 ohm TV ribbon cable), coupled with a balanced antenna transmatch ("tuner"), will deliver comparable performance at less cost. A 135-foot/41.15 meters doublet (dipole) fed with 450 ohm ladder line or 300 ohm TV ribbon cable connected to a balanced tuner will cover all amateur radio bands between 80 and 10 meters.
