Groove A-2Hn sufficient for my needs?

Hello!

I wonder if a Groove A-2Hn would be sufficient for me?
Please see included graphics.

I want to cover both houses (built out of wood) and there are no obstacles to interfere with signal.

the device is fine, what antenna are you planning to use with it? you would have to install some type of an Omni directional antenna

I was thinking about 8dB Omni setup.

Perhaps there is a better antenna alternative?

Thats a good antenna, its what we use.

Are you looking to get signal into the buildings? If so, just ensure that there is no foil backed plasterboard, foil insulation or K-Glass.

Yeah, thats the idea.
Both houses are quite old, so I guess it is safe to believe that there is no foil inside the walls.

Thanks
