Yiziphi izinhlelo zokusebenza zebhodi lokufakwa kwe-SMC emkhakheni wokuxhumana okungenantambo?

Izinhlobonhlobo zezimpondo zisetshenziswa kakhulu emkhakheni wokuxhumana okungenantambo. Uma kuqhathaniswa nezinto zensimbi, izinto ze-FRP zinezinzuzo zesisindo esilula, ukucubungula okulula, ukuthutha nokufakwa, intengo ephansi, i-anti-corrosion, nokunwebeka okuhle. Ngakho-ke, izinto ze-FRP zisetshenziswa ekwenzeni ama-antenna amaningi.

Phakathi kwezinto ezidonsa amehlo kukhona izinhlobo ezahlukene zama-fiberglass reflector antenna. Ama-antenna ama-Parabolic avame ukusetshenziswa kuma-reflector antenna, anokuqondisa okuhle kakhulu futhi ayi-antenna enenzuzo ephezulu. I-FRP ngokwayo ayikwazi ukukhombisa amagagasi kagesi. Uma indwangu yensimbi yensimbi noma ifilimu yensimbi imbozwe ngaphezulu kwayo, iba yindawo enhle ekhombisayo.

Lapho ingilazi yengilazi eqinisiwe yepulasitiki ibunjwa esikhunjeni esimise kahle, indawo ekhanyayo ephezulu ingakhiwa kalula, enenzuzo ephezulu kanye nezindleko eziphansi. Ukuze kube lula ukukhiqiza nokuthutha, izibonisi ezinkulu ze-FRP zivame ukubola zibe amayunithi amaningi amancane, akhiwa njengesiqephu esisodwa, bese ehlanganiswa ensimini; ngezibonisi ezinkulu ze-FRP, ngokuvamile zingenziwa zibe isakhiwo sesemishi, kuyilapho izibonisi ezincane ze-FRP ngokuvamile azidingi ukuboshwa. Isakhiwo esiwumgogodla singakhiwa ngokuqondile ngaphansi kwesisekelo sezimbambo zokuqinisa ezifakwe ngaphambili ngemuva ukuze kuhlangatshezwane nezidingo zokuqina.

Njengamanje, izindlela eziyinhloko zokubumba zezibonisi ze-FRP ukubekwa kwezandla kanye nokubumba kwe-SMC. Ngenxa yokusebenza okuphezulu kwezinto ze-SMC kanye nenqubo yokubumba ye-SMC, ithuthuke kakhulu kunokubeka izandla, kodwa ukutshalwa kwezimali kwayo kukhulu, futhi imikhiqizo ye-SMC ifaneleka kakhulu ukukhiqizwa ngobuningi. Isibonelo, i-TV yesathelayithi yasekhaya ethola izimpondo zozimpondo ezibonisa ukukhanya zinamandla amakhulu emakethe, futhi akhiqizwe ngobuningi futhi asetshenziswa e-United States, Japan, South Korea, Taiwan, naseHong Kong.

Ngakho-ke, ukusetshenziswa kwezinto ze-SMC kule mboni kunamathuba amaningi okuthuthuka. Ngokwemibiko, izwe lami seliqalile ukukhiqiza imininingwane eyisithupha yezimpondo ze-SMC kusukela ngo-1991, okuhlanganisa izinhlobo ezimbili zokwamukela izimpondo, okuhlanganisa uchungechunge lomsakazo kanye nochungechunge lwe-TV yesathelayithi. Phakathi kwazo, uchungechunge lomsakazo selukhona kuleli. Ukuthengisa, nochungechunge lwe-TV yesathelayithi kuthunyelwa kakhulukazi emazweni angaphandle, ngenxa yokuthi i-antenna nesistimu ezweni kufanele kugunyazwe umnyango wezokuphepha ngaphambi kokufakwa nokusetshenziswa, okuthinta ukukhuthazwa kwayo emakethe. Uhlelo lokusebenza alubanzi kakhulu, kepha indawo ekhanyayo yezinye izinto iyinhloko.
