Extend Z-Wave range through external antenna

Hi! I need some help to think right :slight_smile:

I need to extend the Z-Wave signal to reach out with the signal through a wall that wireless signals have problems with. I don’t know that you call this type of walls but it’s like this one: http://staticd.mostphotos.com/f/500x450.watermarks/900000/985055.jpg

I’m looking for an external antenna, that you can mount on both sides of the wall and it’s just make the signals go through the wall.

Are anyone understanding how I mean and if this is possible? Is there any other simple solution?

Put a repeating Z-Wave module on each side of the wall?

I’ve never seen walls like that before, looks like metal diamond plate.
Can you elaborate on what the wall is made of?
I would hate to suggest adding a second antenna to Vera as I don’t know how it would affect the impedance and signal or if this is this a V1 or V2.

JOD.

Also considering that, will probably be my choice :slight_smile: A wall plug on each side of the wall.

JOD: It’s metal and in an industrial building, like a warehouse.
