    Finally a video that answered my questions, normal mode helical antenna or sleeve dipole. I go for sleeve in my LoRa project. Thanks

    Hey man, I just saw your antenna video, and it was very informative. Usually when someone talks about electromagnetic waves (propagation) and antennas, bits and pieces are left out but you did a pretty good job. Keep up the good work!

      Thanks! I am trying to mix little bit theory with practice.

    12:50 What would happen if you inverted the radials 180° so they were facing up, rather than down?
    Thoughts?

    Hey, very informative, thank you.
    You said "therefore end nodes using axial mode helical antennas make no sense", it is just because all the outdoor gateway are using directional antennas, right? Well, would you please give us a recommendation for what is the best antenna type choice of end nodes outdoor device? If you are going to the china antenna supplier market, there is no choice to use these helical antennas. This case would really matter which there was no successful project (in thousand qty) that implement Lora WAN in Indonesia's history.

    "I could not verify if this normal mode helical antenna is a valid design. I have spend many hours but I have given up, sorry...."
    What a diplmomatic way of saying "I tried it. Its crap." :D

    Amazing work. really well explained. Keep up the good work :)
    Some calculations would be nice though.

      I am curious, what kind of calculations?

    Hi, what analyser do you use at 12:48?
