via the ARRL: Arizona Homeowners Association and Hams Agree on Outdoor Antenna Guidelines

The Board of Directors of an antenna-restricted community in Arizona voted overwhelmingly in April to allow radio amateurs to erect certain outdoor antennas on their properties. Some 75 hams live in the 10,000-home Sun City Grand, a self-contained residential community for older adults. An article in the Grand Ham Newsletter by Gordon Bousman, NW7D, called it “a […]

via HACKADAY: Piezoelectric Antennas For Very, Very Low Frequencies

If you want to talk about antennas, the amateur radio community has you covered, with one glaring exception. Very low frequency and Extremely Low Frequency radio isn’t practiced very much, ultimately because it’s impractical and you simply can’t transmit much information when your carrier frequency is measured in tens of Hertz. There is more information […]

via HACKADAY: Fully 3D Printed And Metalized Horn Antennas Are Shiny and Chrome

We’ve seen our share of 3D printed antennas before, but none as well documented and professionally tested as [Glenn]’s 3D printed and metalized horn antennas. It certainly helps that [Glenn] is the principal engineer at an antenna testing company, with access to an RF anechoic chamber and other test equipment. Horn antennas are a fairly simple […]

The SJ9WL-LG5LG Morokulien memorial station on the border of Sweden and Norway is off the air after a large tree, brought down during a severe storm on August 10, caused extensive damage to the station’s antennas.

via HACKADAY: This Mostly 3D-Printed Discone Antenna Is Ready For Broadband Duty

For hams and other radio enthusiasts, the best part of the hobby is often designing antennas. Part black magic, part hard science, and part engineering, antenna design is an art. And while the expression of that art often ends up boiling down to pieces of wire cut to the correct length, some antennas have a […]

via HACKADAY: Putting a Poor Man’s Vector Analyzer Through Its Paces

If anything about electronics approaches the level of black magic, it’s antenna theory. Entire books dedicated to the subject often merely scratch the surface, and unless you’re a pro with all the expensive test gear needed to visualize what’s happening, the chances are pretty good that your antenna game is more practical than theoretical. Not that […]
