Your tutorials are great! There's no room for misunderstanding as every step is clearly explained unlike on pretty much all other tutorials I've ran across. I've learned a lot already by watching 3 videos. Thanks for sharing the knowledge!
Awsome tuturials! Great stuff! will you build an 5/8 wave antenna for 868mhz? Very much interested what the impedance would be and vswr. The radiation lobes should be a little bit longer and flatter compared to 1/2 wave dipole. More range for lorawan! But it should be more difficult to feed them I think?
Sir why should we cut the other 3 ground sma connector feet??is it affecting the result?i am new to lora, especially this radio things...thank you for sharing this knowledge sir.
@@Mobilefish on 23:45 sir, but i understood now. i have one more question, is it possible to make lora dipole antenna just by print it on PCB?and what is the dimension?thank you
You are asking the same question as with the moxon antenna. Theoretical you can, but I do not see the advantage. Printing a dipole or Moxon antenna on a PCB is more a hassle. Are the circuits on the same PCB as the antenna? If so, depending where the circuit is located on the PCB, it can impact the antenna performance. And how is the antenna feeded? By a PCB trace, which can act as an antenna (=interference). As you can see it is not a simple question to answer. Building an antenna (not printing on PCB) is easy to make, easy to test with an antenna analyser and easy to feed (using a coax cable with SMA connector). So, having said this, to answer your question: the same dimensions as mentioned in my tutorial. Keep an eye on the PCB trace thickness.
Okay, please watch th-cam.com/video/ZVo2RkBS14o/w-d-xo.html and checkout: github.com/FabienFerrero/UCA_Board Please note: I have NOT build a PCB antenna myself, so I can not tell you if it is good or not.

sir please make tutorial about folded dipole
Do you have any video on how does affect the diameter of the antenna wire to the range?

Sorry, but I do not understand your question.

@@Mobilefish thank you sir..yes actually i'm looking for best fitted internal box antenna for my node.
