Hi tech antenna feed under preparation, model known as 'ENSI rypsiöljy'.
Empirical tests have shown that small amounts of rust barely affect the

transmitting live video show from Viestikallio.
The first requirement for receiving tv transmission is getting electricity.
(The second is locating the direction of the transmitting antenna.)
