An article in our local newspaper reminded to me, that birds have more and more problems to find places where they can build their nest and grow up their squabs (not only in cities).
I asked myself if I could help and when then how.
So I decided to install on the mount of my ADS-B antenna a nest box.
The hole of the nest box should look to the east or south-east, so I had to turn the antenna and mount the nest box there were the antenna was.
Because spring was coming, it took only a few hours and the nest box was occupied by some birds.
Mounting a nest box nearby to the ADS-B antenna can generate other benefits: In our flat satellite-antennas for TV are forbidden, my ADS-B antenna was not 100 percent legal or illegal and sometimes a subject of discussions with the landlords and neighbours.
Now my landlord explained to me, that my mount is in his view an acceptable nest box with an antenna, and a neighbour asked me if the radiation of the antenna would harm the birds. I explained to her that this is a passive antenna that nor harm the birds nor her living beside it.
Before I mounted the nest box, the subject “antenna” was negative, now it has changed to positive.
With these lines I would invite you to check, if you could improve your antenna with a small effort.
Best regards from Switzerland.
