通(tong)(tong)(tong)信(xin)(xin)塔(ta)由塔(ta)體、平臺、避雷(lei)針、爬梯、天線支(zhi)撐等鋼構件(jian)組(zu)成，并經熱鍍鋅防腐處理，主要(yao)用于微(wei)波、超短波、無線網絡信(xin)(xin)號的(de)(de)傳輸(shu)與發射等。為了保證無線通(tong)(tong)(tong)信(xin)(xin)系統的(de)(de)正常(chang)運(yun)行，一般把通(tong)(tong)(tong)訊(xun)(xun)(xun)天線安置到最高點以增(zeng)加(jia)服務半徑(jing)，以達(da)到理想的(de)(de)通(tong)(tong)(tong)訊(xun)(xun)(xun)效(xiao)果(guo)。而通(tong)(tong)(tong)訊(xun)(xun)(xun)天線必須有通(tong)(tong)(tong)訊(xun)(xun)(xun)塔(ta)來增(zeng)加(jia)高度,所以通(tong)(tong)(tong)訊(xun)(xun)(xun)鐵塔(ta)在通(tong)(tong)(tong)訊(xun)(xun)(xun)網絡系統中(zhong)起了重要(yao)作用.
