That a lot for your answer. I would like to add a couple of questions.
First I heard that LoRa is a limit of 2dB. I am surprised and I think it a wrong information as TTN propose higher antenna. Can 8dB works as well. Lately I planned to buy a GP901C antenna. (5-8Db). I supposed, if my gateway has a such antenna, I could be farer with my nodes… That’s right?
(I understood, I have to be carefull with ERP and VSWR)
For now I will not buy a new antenna for my test of this week-end, For one of my node, I am going to use a 8cm wire, as an antenna. I would like to test until which distance a gateway can receive message from the node.
Then I am worried about a wired antenna as it’s shown in that picture
Can have the same result than with this 2dB antenna?
Personnely, I do not think the wired antenna will be good as a normal antenna, but I just would like to ask you point of view, as I oft read somethink like this:"… you can as well use a wired antenna… if you do not have an antenna"
Will be the different largely different?
Thank a lot and have a nice day
