① 中繼臺天線為啥要裝(zhuang)在高處?

中(zhong)繼臺的(de)信號是通過天(tian)線(xian)(xian)發出(chu)去的(de)，所以為(wei)了信號覆蓋(gai)范圍大，天(tian)線(xian)(xian)需要裝在高(gao)處。

② 中(zhong)繼臺(tai)必(bi)配置雙工(gong)器嗎?

看個人需求的。需要了解，雙工器只是為了讓中繼臺收發(fa)共(gong)用一條(tiao)天(tian)(tian)(tian)線(xian)(xian)。如果不(bu)裝(zhuang)雙工器，中繼臺要安裝(zhuang)兩條(tiao)天(tian)(tian)(tian)線(xian)(xian)，并且接(jie)收天(tian)(tian)(tian)線(xian)(xian)和發(fa)射天(tian)(tian)(tian)線(xian)(xian)，需要保持一定的距離，否(fou)則收發(fa)會互相干擾。

③ 中(zhong)繼臺雙工器(qi)可以自己調試嗎(ma)?

如果(guo)自己夠專(zhuan)業可以(yi)調(diao)(diao)(diao)試；如果(guo)不(bu)專(zhuan)業，雙工(gong)器(qi)的調(diao)(diao)(diao)整由工(gong)廠進(jin)行，否則(ze)調(diao)(diao)(diao)試不(bu)當易燒壞中(zhong)繼臺的高放電(dian)路，請引起重視不(bu)得隨意調(diao)(diao)(diao)。
