Swiss section HB9AG – USKA Aargau organizes on Friday 2 October 2026 a technical meeting devoted to the practical design and analysis of amateur-radio antennas. The event will take place from 20:00 to 21:00 at the Ochsen restaurant in Lupfig. Admission is free.

The meeting will focus on using modern tools for antenna design and optimization. The organizers wish to draw attention, among other things, to computer simulations, the Smith chart, and the proper interpretation of results obtained from software and measuring instruments.

The event announcement carries the telling subtitle „a fool with a tool is still a fool”. The meeting is intended to demonstrate that merely possessing advanced software or an instrument does not replace understanding the phenomena occurring in an antenna system. The program includes demonstrations presented from the perspective of a software engineer and a university professor.

The organizer is HB9AG, namely the Aargau section of the Swiss amateur-radio association USKA. The club's technical activities include, among other things, antennas, homebrew projects, repeaters, and field operations.
