Arduino UNO WiFi with external antenna

Using Arduino IDE 1.x
1

Hi, I am new here so just bear with me....

I connected an external antenna to my UNO WiFi board, and I cannot
find information anywhere about if I have to make changes so that the
external antenna will be operative.
It looks like the on-board antenna is still active....

Anyone?

Thanks.
I've already seen it, and it does not explain everything..
I will remove the onboard antenna and see what happens...

Do you have the schema?

Uno WiFi Dev Ed schema

Hi.
Yes, I have the schematics, but not the board-layout.
I removed the internal antenna(X3), and added a link to the CX1 connector.
The modification works great.
Thank you Juraj for helping out. :slight_smile:

I also need to install an external antenna but it's not clear what I need to do and the link in reply #1 no longer works.
