WIFI天線(xiàn)也就是常說(shuō)的天線(xiàn)無(wú)線(xiàn)路由器。無(wú)線(xiàn)路由器范圍包括單天線(xiàn)、雙天線(xiàn)和三天線(xiàn)后續(xù)還有多天線(xiàn)路由器。**近正大信維小編有遇到一些客戶(hù)咨詢(xún)wifi天線(xiàn)的天線(xiàn)數(shù)量不同的區(qū)別有哪些，下面我們就來(lái)具體看一下。1、雙天線(xiàn)和單天線(xiàn)區(qū)別在是雙發(fā)雙收，還是單發(fā)單收，前者局域網(wǎng)速度是300M，后者局域網(wǎng)一般是150M。雙天線(xiàn)路由器在使用時(shí)比較好不要讓兩條天線(xiàn)平行，了兩者比較好成135度張角，即一條天線(xiàn)與桌面垂直，另一條與桌面成45度角。2、單天線(xiàn)路由、雙天線(xiàn)路由、三線(xiàn)四線(xiàn)有區(qū)別，但對(duì)于實(shí)際使用過(guò)程中的影響并不大，這包括信號(hào)覆蓋、信號(hào)強(qiáng)度，天線(xiàn)多速度快就更是無(wú)稽之談了。拋開(kāi)已經(jīng)很少見(jiàn)的單天線(xiàn)，剩下的“多天線(xiàn)”都只是實(shí)現(xiàn)MIMO技術(shù)的“介質(zhì)”或者說(shuō)是“工具”，區(qū)別在于使用的架構(gòu)不同而已：常見(jiàn)的雙天線(xiàn)產(chǎn)品主要用1T2R或2T2R，三天線(xiàn)產(chǎn)品則用到的是2T3R或3T3R。理論上，增加天線(xiàn)數(shù)量會(huì)減少信號(hào)覆蓋盲點(diǎn)，但我們通過(guò)大量的評(píng)測(cè)證實(shí)，南通5G天線(xiàn)，這種差異在普通家庭環(huán)境中完全可以忽略不計(jì)，南通5G天線(xiàn)。而且，就像內(nèi)置天線(xiàn)不輸外置一樣，三天線(xiàn)覆蓋不如雙天線(xiàn)的情況也絕非個(gè)例，說(shuō)到底產(chǎn)品質(zhì)量也是一個(gè)重要因素。至于信號(hào)強(qiáng)度和“穿墻”則取決于發(fā)射功率，這個(gè)東西工信部作過(guò)規(guī)定，南通5G天線(xiàn)。天線(xiàn)不可以放倒使用，放倒以后駐波會(huì)很大，損傷機(jī)器。南通5G天線(xiàn)</p><div

style="text-indent:25px">車(chē)載天線(xiàn)**理想的安裝位置就是車(chē)頂?shù)恼?*，天線(xiàn)利用磁性吸盤(pán)吸附在車(chē)頂上，雖然它與金屬材質(zhì)的車(chē)頂通常是絕緣的，但是兩者之間存在不小的電容，在高頻狀態(tài)下形成通路，車(chē)頂就被當(dāng)作天饋系統(tǒng)的地網(wǎng)，和天線(xiàn)共同構(gòu)成車(chē)載電臺(tái)的天線(xiàn)系統(tǒng)。 ? ? ? 不過(guò)實(shí)際生活中，受各種外在條件的限制，譬如天線(xiàn)較長(zhǎng)影響進(jìn)入車(chē)庫(kù)，另外為防止磨刮車(chē)漆、顛簸脫落，或者使用高增益的較大、較重的天線(xiàn)時(shí)，車(chē)載天線(xiàn)往往并沒(méi)有安裝在此位置，而是利用不銹卡鋼座安裝在汽車(chē)的行李架、備胎架、前后護(hù)杠、側(cè)面邊框、后備箱蓋甚至排氣管上，更有甚者直接放入車(chē)內(nèi)。改變車(chē)載天線(xiàn)的位置，實(shí)際上改變的是天線(xiàn)系統(tǒng)的地網(wǎng)，駐波比自然也會(huì)跟著改變。除了車(chē)頂正**，在其他位置天線(xiàn)還能調(diào)整到理想的工作狀態(tài)嗎？回答是肯定的，只要安裝時(shí)使用駐波比功率表（即SWR表），或直接使用天線(xiàn)測(cè)試儀，邊測(cè)量邊調(diào)整選擇的位置，保證天線(xiàn)駐波比小于1.5，就完全可以放在車(chē)頂以外的其他任意地方。從性能價(jià)格比出發(fā)，人們常常選用柵狀拋物面天線(xiàn)作為直放站施主天線(xiàn)。</p><div
