My name is Pascal and I come from Switzerland!
I have a large yard and I need walkie tokie that work fine in and out the building.
In this building I have wall larger more than 1.5 meters!
I need a minimal range, like 350-400 meters but with strong power to go through the walls! The walls are made of reinforced concrete!
My budget is around 450-500 Swiss Francs.
What kind of walkie tokie I need? (PS: I need 4 walkie tokie)
And where can I buy it?
