Una meridiana verticale per la ricezione satellitare

In these last years the DBS (Direct Broadcasting Satellite) system has induced a large spreading of dish installations even in ancient cities and invaluable zones. In many cases they have compromised the beauty of the buildings and in some cities the wild installation of such antennas have been forbidden. This paper wants to be an answer to this problem by proposing a low cost solution which makes easier the antenna integration with the existing environment. In particular, an example where the proposed configuration was used to realize a vertical sundial is presented. Radiation patterns and electrical characteristics are also reported.
