Nibikoresho bya satelite byo guhitamo nuburyo bwo kubigenzura mbere yo kugura

Televiziyo ya Satelite irashobora kugera mu mfuruka ziherereye ku isi, aho usanga nta batanga bisanzwe ndetse niminara yo gutangaza. Sisitemu zihari zashyizweho zashyizweho igihe icyo aricyo cyose. Ibyokurya bya satelite bizatanga ishusho y’amabara kandi asobanutse. Kwakira ibyiringiro biterwa nigenamiterere nibikoresho bya tekiniki. Umugozi wa “isahani” urashobora kuzamura no kubungabunga ibipimo byiza, no kugabanya ubushobozi niba uhisemo nabi.

Igikoresho cya satelite igikoresho

Intego ya kabili ya tereviziyo niyihe ntego:

• zana ibimenyetso kuva antenne kuri TV hamwe nigihombo gito;
• kurinda amashanyarazi aturuka hanze;
• komeza imikorere munsi yubukanishi, mubihe bigoye.

Umugozi wa coaxial wihanganira imirimo. Birakwiriye gutambuka (kwakirwa ukoresheje umunara wa TV cyangwa antenne yo mu nzu) hamwe na satelite. Kubwibyo, nta tandukaniro riri mubishushanyo. Gusa ibikoresho bitandukanye birakoreshwa.
