Tall mount is good to get the GPS mag sensor away from electromagnet power wires, so I usually use tall mount.

I don't know how much help the "anti-interference" advertisement is.  :)

Leave the GPS wires long unless you have an APM style of GPS where GPS is on one connector and mag (I2C) is on another connector and you are having problems with mag communications.  In that case, a shorter mag cable can help... but the best thing to do about that is to solder some pull up resistors (say 2k-5k) inside the GPS/mag case (SDA to +3.3V and SCL to +3.3V).

Thanks for your answer so clear.
I would like use this tall mount because first it look like more resistant and actualy i can't use mag from gps because when the quad is on the ground i see with the gcs the quad moving!
It's better to use both mag or just gps mag?
The connexion is just with 1 cable (4 wires) connected to the main port. It's a naza dji compass gps.
If i have always this problem with the new tall mount i will try to put resistance but i just have a big resistance 4.2kohms (50w) so will not very pratic 😂😂

That is usually a mag problem: mag orientation not correct in mount or configuration, or mag not well calibrated, must use "Aux Only"

Resistors not needed for DJI GPS.

I have received my new gps mount...
But it's to little for my dji naza gps 😰😰
I think is for mini compass gps.
And actually the weather is rainning and winding very strong!
My sunday... 😭😭😭
Stupid winter 😝😝
