About this model
This is part of my Long Range Weather Station project : I wanted to increase range for my 868 MHz lora devices. I followed the link of this "biquad calculator" : Biquad antenna is a kind of loop antenna with a simple design, easy to build and offers a good characteristic of directivity and gain for point to point communications. It consists of two radiating elements made of connected squares with the side length equal to ¼ mid-band wavelength. I built this simple jig which can be used both for folding the 2mm coper wire, but also as a permament holder. To even increase the range I should have added a metal ground plane to reflect the back lobe to the front side. Without this ground plane my antenna acts more like an "omni" antenna. But who cares ? It works fine ! Print it in PET or PETG to…
