ANT0025PO Antenna ea Log-periodic e tšoaroang ka letsoho
| Moetapele-mw | Kenyelletso ea Antenna ea Log-Periodic e ts'oaroang ka letsoho |
Ho hlahisa Cheng du leader mcrowave Tech.,(moetapele-mw) antenna e ts'oaroang ka letsoho ea log-periodic, tharollo ea ho qetela ea ho eketsa matla a lets'oao le tšireletso ho 800 ho isa ho 9000 MHz frequency range. Antenna ena e kopaneng empa e le matla e etselitsoe ho ts'ehetsa lihlopha tsa maqhubu a cellular, PCS, LTE, 4G LTE le Wifi/WiMAX, e e etsa sesebelisoa sa bohlokoa ho mang kapa mang ea hlokang likhokahano tsa mohala tse tšepahalang le tse sebetsang hantle.
Antenna e tšoaroang ka letsoho ea nako e telele e na le phaello e bataletseng ea 6 dBi, e koahelang L/S/C/X ka ho nepahala le ho nepahala ho holimo, ho netefatsa hore o lula o hokahane ho sa tsotelehe hore na o hokae. E ikhetha ho antenna ena ke moralo oa eona o feto-fetohang o otlolohileng le o otlolohileng oa log-periodic, o fanang ka maemo a fetohang le maemo ao ho seng a kileng a ba teng ho fihlela litlhoko le tikoloho ea hau.
E etselitsoe bakeng sa ho tšoarella le ho sebetsa, antenna e tšoaroang ka letsoho ea log-periodic e na le radome e entsoeng ka polasetiki e matla, e tlaase, e etsang bonnete ba hore e khona ho mamella maemo a thata le ho tsoela pele ho fana ka ts'ebetso e tsotehang. Tšebeliso ea eona ea sethunya e potolohang e eketsa boiketlo le boiketlo ba tšebeliso, e u lumella ho fetola antenna habonolo ho ntlafatsa kamohelo ea matšoao.
