Antennas : 30M- VDA Antenna for 30m
new
- This project documents the construction and enhancement of a 30m Vertical Dipole Array (VDA) antenna inspired by Remco 7QNL article. Initial design utilized an 18m Spiderbeam pole and a 4m boom. Improvements included a lighter boom structure using fishing rods and a revised coaxial arrangement for enhanced mechanical stability.

- Phased Array Antennas
- Phased array antennas are composed of multiple individual antenna elements that can have their phase and amplitude controlled to steer the main beam direction in real-time. They are used in radar, communications, and electronic warfare, and offer improved gain and reduced side lobes. A comprehensive document on Phased Arrays include techniques to increase the Antenna Gain and change the Radiation Pattern

- RF-Quiet Solar PV for Ham Radio
- This article discusses the potential for solar power systems to coexist harmoniously with amateur radio, challenging the notion that they are inherently incompatible. Drawing from personal experience, the author emphasizes the importance of selecting RF-quiet components, focusing on series-string Sunny Boy grid-tie inverters. The article also highlights considerations for system design and limitations based on roof orientation, shading, and array size. Overall, it presents a valuable perspective on creating a radio-friendly solar PV setup.
