Game da ERP Tasirin Ƙarfin Radiated

Kafin kayi kiyasin radius murfin mai watsa FM ɗin ku, kuna buƙatar koyo game da manufar ERP (ingantacciyar wutar lantarki), wacce ake amfani da ita don auna ƙarfin mitar rediyo na kwatance.

Tsarin ERP shine:

ERP = Ƙarfin watsawa a cikin Watt x 10 ^ ((Gain tsarin eriya a cikin dBb - saƙon kebul) / 10)

Don haka, don ƙididdige ERP kuna buƙatar sanin abubuwa masu zuwa:

• Ƙarfin fitarwa na mai watsawa
• Asarar kebul na coaxial da aka yi amfani da shi don haɗa mai aikawa zuwa eriya.
• Tsawon kebul na coaxial.
• Nau'in tsarin eriya: dipole a tsaye polarization, madauwari polarization, eriya ɗaya, tsarin tare da eriya 2 ko fiye, da sauransu.
• Ribar tsarin eriya a dBb. Riba na iya zama tabbatacce ko mara kyau.

Ga Misalin Lissafin ERP:

Ƙarfin Mai watsa FM = 1000 Watt

Nau'in eriya = 4 bay dipole polarization tsaye tare da samun 8 dBb

Nau'in kebul = ƙananan sako-sako 1/2"

Tsawon kebul = 30m

Attenuation na kebul = 0,69dB

ERP = 1000W x 10^(8dB - 0,69dB)/10 = 3715W
