LoRa/LoRaWAN tutorial 49: Moxon Antenna

If you like this video and want to support me, go this page for my donation Paypal or crypto addresses: This is part 49 of the LoRa/LoRaWAN tutorial. In this tutorial I will explain what a Moxon antenna is and how to build one. The Moxon antenna is a simple and mechanically robust two-element parasitic array antenna created by amateur radio operator Les Moxon. This directional antenna is equivalent to a two element Yagi-Uda antenna. It has a reflector and a driven element but no directors. The two elements are mechanically connected by two insulators. The antenna has a large beam width and a very good Front-To-Back ratio. To find the Moxon antenna dimensions you can use the following calculators: I have used the 4NEC2 antenna modelling software to verify the design. How well does my self build Moxon antenna performs? To answer this question, two performance tests will be conducted. Performance test A: The Moxon antenna is attached to an end node, which is located inside a building, and transmit messages which will be received by nearby gateways in my area. In this test I am only interested which gateways were able to receive the transmitted sensor data. The test will be repeated using a sleeve dipole antenna. Performance test B: The Moxon antenna is attached to an end node and transmit messages which will be received by a dedicated gateway 6 meters away. Both devices are indoors. The average RSSI is calculated. The test will be repeated using a ½λ dipole...
