Antenna radome

thingiverse

This is a quarter wavelength antenna shielded by a protective cover. To connect it, use a wire (such as 8.6 cm for 869.85 MHz) soldered directly onto the printed circuit board. The OpenSCAD file is available so you can easily adjust the dimensions if you need to change the frequency. The protective cover can be securely attached to the pcb. A picture showing both the antenna with and without the cover is also provided.
