Description

Support pour fabriquer une antenne Ground plane 868MHz.
Permet la mise et le maintien à 45° des réflecteurs.
Support intégrant capot, allonge, pied et coude à 90°. Pour un montage vertical, pas la peine d'imprimer le coude à 90°.
Le câble coaxial peut arriver par dessous (trou dans le pied) ou sur le coté de l'allonge.
Ce projet est inspiré du projet de dedehai : https://www.thingiverse.com/thing:2849393
Voir son blog : https://bashtelorofscience.wordpress.com/2018/04/03/diy-lora-antenna/
Il est conçu pour être utilisé avec du câble électrique de 1.5mm2.
ATTENTION : si vous utilisez le capot pour couvrir l'anttente, celui-ci rajoute une capacité. Il faut donc ajuster l'antenne. Je vous recommande fortement l'utilisation dun VNA (style NanoVNA).

Support to make an 868MHz Ground plane antenna.
Allows the placement and maintenance at 45° of the reflectors.
Support integrating hood, extension, foot and 90° elbow. For vertical mounting, no need to print the 90° elbow.
The coaxial cable can arrive from below (hole in the foot) or on the side of the extension.

It is designed to be used with 1.5mm2 electrical cable.
WARNING: if you use the hood to cover the antenna, it adds capacity. The antenna therefore needs to be adjusted. I strongly recommend using a VNA (NanoVNA style).
