@mfalkvidd Thank you for your answer. I will give it a try for this price.

I am looking for a possibility to extend an ir signal. And I don't mean one with a loose power supply..
I use an IR remote control that can send and receive. The device to be programmed can also send and receive. Only this is at a meter or 2.5 high. Targeting the remote control is therefore quite difficult and must then take a ladder.
Does anyone have an idea if this is possible?

Tanks.

When this question is on the wrong place, sorry for that.
