My house as radio station :)

When I started building our house, I was not active as radio amateur. That's bad, since I had a nice opportunity to make a superb grounding in the beginning. But then the second floor was built, I built in some antenna channels in the roof and walls. Also I prepared for different options that future might bring.

My attic. Pipes go down to my ham shack inside the roof isolation and inside the walls.  Antenna wires are pushed into the pipes...

...and they appear here, behind my shack. The shack-side looks like this, since it is not finalized yet...
