The “Flower Pot” antenna is a clever twist on the half-wave, end-fed dipole antenna design that incorporates the coax feedline directly into the construction of the antenna. All credit for the design and instructions goes to John Bishop (VK2ZOI). Learn more about the history and development of the antenna, together with detailed plans and instructions by visiting John’s website:
Amateur radio enthusiasts in the US will be interested in Faraday, an open-source digital radio that runs on 915 MHz, which amateur radio enthusiasts may know better as the 33 cm band.
You can transmit on 915 MHz without a license (in the US), taking advantage of the Industrial, Scientific, and Medical (ISM) exemption. This means that there’s commodity hardware available for sending and receiving, which is a plus. But you can’t do so with any real power unless you have an amateur radio license. And that’s what makes Faraday interesting — it makes it very easy to transmit and receive digital data, with decent power and range, if you’re licensed. The band is currently under-utilized, so go nuts!
More than a hundred years ago, a few intrepid amateurs began experimenting with a new means of communications known then as “wireless.” These protohackers — soon to be known as hams — foretymologically obscure reasons — began building their own electronics gear, hoping to use it to communicate with others. By the early 1920s, amateur radio operators were talking with and even transmitting images to complete strangers on the other side of the world.
