Lokacin zayyana kogon, ƙungiyar injiniyoyinmu sun yi la'akari da cikakkiyar ma'amalar cikawar sifili da karkatar da katako: 

1. Matsakaicin kusurwa: 0.5 digiri
2. Samun Eriya: 11 dB
3. Radiation (Horizontal): ko'ina.

Firam ɗin bakin karfe yana da ayyuka na shigarwa da ɗaure don tabbatar da kwanciyar hankali na raƙuman radiyo, kuma yana da ayyukan radiation da kariya ta haske. 

Tun da babban rami yana da sauƙin lalacewa, ƙirar bakin karfe na iya tabbatar da tauri da kwanciyar hankali na rami na radiation. 

Za a iya gyara firam ɗin bakin karfe kai tsaye a gefen hasumiya ba tare da canza siffar rami ba.

Menene Ya Kunshi Cikakken Tsarin Eriya na VHF?

Wadannan su ne mafi asali na VHF tsarin eriya aka gyara:

1. Eriya Ramin VHF mai zaman kansa
2. Ramin kariya (rufin ramuka ko cikakken radome da aka rufe)
3. Eriya coaxial USB (yawanci kebul na ciyarwa, misali 1-5/8'' coax)
4. Kebul mai ciyarwa matsi
5. Antenna Dutsen Mast/Bracket

Kuna son ƙarin koyo? Don Allah samun shiga tare da ƙungiyar tallace-tallace mu!

Tabbas, ban da wannan kayan aiki, yayin aikin shigarwa, har yanzu kuna buƙatar kula da:

1. Wurin shigarwa na eriya. Kuna iya hawa eriyanmu na VHF ko dai a saman hasumiya, a gefen hasumiya, ko a kife. Idan an ɗora shi a gefe, yi la'akari da faɗin hasumiya ko diamita na mast don kyakkyawar radiation kwance. Gabaɗaya, tsayin raƙuman raƙuman ruwa na VHF sun fi tsayi kuma diamita mast yana da ɗan tasiri.
2. Don ƙarin fa'ida. Tari eriya biyu ko fiye a tsaye. Zaɓin da ya dace na tsawon layin watsa na mai sauya layi da mai ba da abinci na coaxial tsakanin nodes zai iya fi dacewa magance matsalolin tsaka-tsakin sifili da karkatar katako.
3. Tsayin ƙasa
4. Tsawon shigarwa na eriya
