Hentenna for Meshtastic/Meshcore

This is a Hentenna for Meshtastic/Meshcore or other mesh projects.

The Hentenna is a unique type of directional antenna developed in Japan in the 1970s by Tadashi Okubo (JH1YST) and Shinji Someya (JE1HJA).

This version  takes much less time to 3D print than [3]. It's a 3 part set, fastened with zippties, and prints flat without supports.

There are 3 sets of Meshtastic LoRa antenas: 915 MHz for North America, 868 MHz for Europe, and 433 MHz for Asia.

Let me know your experimentations with this!
