Tarihi

Eriyar ƙahon faɗaɗa eriya ce da ake amfani da ita don watsa igiyoyin lantarki, kuma ana iya gano tarihinta tun a shekarun 1930. Wani masanin falaki Karl Guthe Jansky Ba’amurke ne ya fara ƙirƙira eriyar ƙaho na broadband a shekara ta 1932. Ya yi amfani da eriyar “ƙaho” ta musamman don karɓa da auna raƙuman radiyo a sararin samaniya.
