Leslie Moxon, G6XN, invented a two-element in the 1950es, named after him. Less Moxon published an article in a QST magazine from 1952 titled Two-Element Driven Arrays describing his antenna.
A Double Bazooka Antenna is a broad-banded half-wave Antenna. This antenna can operate efficiently across an entire band without needing an antenna tuner. In the 1940es, the MIT staff designed and developed this antenna as a radar antenna for the military. Like a dipole, the Double Bazooka is a balanced …
I gave a presentation on antenna modeling software to a couple of clubs in California and Oregon. From the physical antenna design to the matching network, we designed the antenna live with the participants. Here is a little more about the talk: During the first part of the talk, we …
The 2021 Field Day was the first time member of the San Mateo Radio Club met in person since the pandemic. It was nice to see friends again after so long, but the most enjoyable part was to be in a group of people working toward the same goal …
This year for Field Day, our club decided to build a new multi-band antenna for 80 and 40 meters. The antenna had to have enough bandwidth to use the entire band without using an antenna tuner.
Our main goal as Amateur Radio Operators is to make sure that as much of the power coming out of the radio as possible is radiated by the antenna. The maximum power transfer occurs when the power source, the radio in our case, and the load or the antenna are …
Is Resonance required? This is an extract from the ARRL Antenna book1 Please recognize that an antenna need not to be resonant to be an effective radiator. There is in fact nothing magic about having a resonant antenna, provided of course that you can devise some efficient means to …
