Do you have a HackRF or RTL-SDR that's deaf? You can't fix everything in software - it all starts with the antenna! There will be a brief show & tell of some DIY antennas and the design compromises behind them, then we'll try our hand at building a simple corner-reflector style 5.8GHz directional antenna suitable for WiFi fox-hunting (while stocks last). We also plan to have some antenna analyzers on hand - in order of certainty: 240MHz, 1.5GHz, and if we're lucky - a 20GHz analyzer loaned by a generous local radio club (CRARC) member. So if those cantennas, DIY helicals/clover-leaf designs or commercial antennas aren't working - come get it measured! We'll hopefully have the gear available throughout both days of the conference.
