prusaprinters

<p>This is a very efficent dipole antenna for Lora network.<br/> It is tuned for 868MHz frequency</p> <p>more information here : <a href="https://github.com/CongducPham/tutorials/blob/master/Low-cost-LoRa-IoT-outdoor-step-by-step.pdf">https://github.com/CongducPham/tutorials/blob/master/Low-cost-LoRa-IoT-outdoor-step-by-step.pdf</a></p> <h3> Print Settings</h3> <p><strong>Notes:</strong></p> <p>print it with the connector UP to avoid supports</p> <h3> Custom Section</h3> <p><strong>wiring</strong></p> <p><div><p>cut two pieces of thin wire (1mm)<br/> solder one end into the SMA connector on the ground ring</p> <p>then solder the second one into the central pin</p> <p>bend both of them into opposite directions</p> <p>cut precisely the tip so that they will be 86 mm length measured from the outside of the sma connector</p> <p><strong>antenna cover</strong></p> <p><div><p>insert the tips of the wires into the frame<br/> gently slide them so that the connector fits in place</p> <p>epoxy glue the cover (don't put too much glue if you want to be able to reuse the connector)</p> </div></p></div></p> Category: Engineering
