Description
🔄 Update v1.1: The antenna has been retuned and optimized for 868 MHz for improved SWR performance.
This version provides better matching and overall efficiency.
📡 Moxon Antenna for 868 MHz (Meshtastic / LoRa)
🧭 A directional Moxon antenna optimized for the 868–869 MHz EU868 LoRa / Meshtastic band.
It provides improved range and signal stability compared to standard whip antennas.
The antenna is configured for vertical polarization by default but can easily be rotated for horizontal use.
⚙️ The model includes two mounting versions:
🔩 The radiating elements are made from solid copper wire taken from a 1.5 mm² electrical cable — single-core, twin, or three-core types all work fine.
Connection is made via an SMA pigtail — a short coaxial cable with an SMA connector.
📎 Photos of these two components — the copper wire and the SMA pigtail — are attached in the documentation section below.
All printed parts are designed for standard PLA filament.
