thx :wink:

:question: The diagram looks like a caltrop. Antenna should be mounted vertically.

Yeah verticaly,
i mean the ā€œdipolsā€ which direction?

It wonā€™t make a ā€˜lotā€™ of difference if the antenna and ground radials are elevated above the structure.

The antenna is at the second floor at the window.
The house has 4 floors ;(

How close to the wall or mounting pole?

30cm to the wall ;(
tomorrow i take a pic
