Antenna ea ka ntle 470-510MHz Flexible whip antenna
Kenyelletso ea Sehlahisoa
470-510MHz flexible whip antenna ke antenna ea puisano e se nang mohala e sebetsang hantle haholo.E sebelisa sehokelo sa banna ba SMA ho tsamaisa khokahano le lisebelisoa tse fapaneng mme e loketse ho sebelisoa libakeng tse kantle.Matla a mahlaseli a antenna a fihla ho 53%, ho bolelang hore e ka khona ho fetolela matla a motlakase ka mokhoa o nepahetseng hore e be matla a mahlaseli le ho fana ka phetiso e tsitsitseng ea matšoao.Ka nako e ts'oanang, phaello ea eona ea tlhōrō e feta 1 dBi 'me e na le matla a matla a ho ntlafatsa matšoao, a ka atolosang sebaka sa puisano.
Antenna ena e sebelisoa haholo maemong a fapaneng, ho kenyeletsoa metering e bohlale, li-gateways, tlhahlobo ea waelese le marang-rang a marang-rang.Lefapheng la metering e bohlale, e ka sebelisoa ho buisana le limithara tsa motlakase tse bohlale, limithara tsa metsi le lisebelisoa tse ling ho fihlela pokello ea lintlha tse bohlale le ho beha leihlo hole.Mabapi le li-gateways, e ka hokahana le lisebelisoa tse fapaneng tsa liheke ho fana ka tšehetso e tsitsitseng ea puisano ea waelese.Lits'ebetsong tsa ho lebela tse se nang mohala, e ka sebelisoa bakeng sa phetiso ea matšoao ea lik'hamera tsa ho shebella video le lisebelisoa tse ling ho netefatsa boleng ba video le botsitso.Ka marang-rang a marang-rang, e ka sebelisoa e le mokhoa oa puisano pakeng tsa lisebelisoa tsa node ho lemoha phapanyetsano ea data le mosebetsi oa tšebelisano pakeng tsa lisebelisoa.
Antenna e na le mokhoa o motle oa phetisetso ea omnidirectional, ho bolelang hore e khantša mats'oao ka ho lekana ka mahlakoreng 'ohle, e fana ka tšireletso e pharaletseng.Sena se etsa hore e be se loketseng bakeng sa lits'ebetso tse hlokang ts'ireletso holim'a libaka tse kholo, joalo ka meaho e meholo, tikoloho ea litoropo, joalo-joalo. Ho sa tsotellehe hore na e ka hare kapa ka ntle, antenna ena e ka fana ka tšehetso e tsitsitseng le e sebetsang ea puisano ea mohala.
