This project details building a multi-band antenna for park activations. The author constructs a random wire antenna with a 9:1 UnUn for improved performance. Winding the toroid core proved challenging, but the completed antenna shows promising results in initial tests with an analyzer. Further field testing is planned for a future activation.
This webpage allows you to create custom QSL cards (confirmation of radio contact) as PDFs for printing. You can personalize them with images and information. The cards are standard size (5.5″ x 3.5″) but can be adjusted slightly for easier printing on regular paper. You’ll need Adobe Acrobat Reader to view the PDFs. There’s also an option to create a free account to save your information for future cards.
The author describes building a remote switch box to control the direction of two reversible Beverage antennas. The switch uses a buried cable and relays to select the desired antenna direction from the shack. The design is simple and uses common components.
A small Yagi antenna for camper van. It is made of aluminum tubing, breaks down for storage, and works well for communicating with others. He built it in an afternoon and it gets good signal. The antenna is lightweight and can be packed up to fit inside his van while traveling
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.
