Standard Gain Horn Antenna
Standard gain horn antennas are used as calibration devices that measure the gain of other antennas.
These antennas are made up of a combination of a Waveguide to Coax Adapter and Standard Gain Horn with Waveguide Input. It is a kind of simple combination but with great care and attention to create an antenna with accurate and suitable specs.
FT-RF Standard gain horn antenna product series includes waveguide sizes WR28, WR42, WR51, WR62, WR75, WR90, WR112, WR137, WR159, WR187, WR229, WR284 and WR340, WR430, WR510, WR650, WR770, WR975, WR1150, WR1500, WR1800, WR2100, WR2300, with broadband waveguide horn antennas have frequency capabilities ranging from 320Mhz to 40 GHz depending on type and style. with the gain of 10dBi, 15dBi, 20dBi and 25dBi.
Standard Gain Horn Antenna Applications:
- - Antenna measurement
- - Radar Detection System
- - Wireless Communication
- - Spectrum Monitoring
- - Electromagnetic interference Testing (EMI test)

建設局要求施工團隊緊急進行修復作業台中市「市政路延伸工程」第二標（環中路至安和路段）於穿越國道一號辦理管冪推進施工期間，因地質條件影響，造成國道路面局部微幅沉陷情形。市府建設局今日表示，市府秉持「安全第一、即時處置」原則，第一時間即要求施工團隊進場修復，並同步與交通部高速公路局建立監測與通報機制，目前國道行車狀況正常，請用路人安心。
「市政路延伸工程」穿越國道一號
建設局長陳大田表示，市政路延伸第二標工程須於國道一號下方進行管冪推進作業，施工難度高、工法複雜，屬國內少見的大型地下推進工程。針對今日國道一號北上車道發生局部微幅下陷情形，建設局表示，接獲通報後已立即通知高公局，並依程序啟動緊急交通維持計畫。施工單位已立即集結人力與機具進場搶修，預計將於晚上9點左右搶修完成。施工期間封閉北上部分車道，提醒用路人注意減速慢行。
建設局重申，市府將持續以嚴謹態度督導施工團隊，強化監測與安全管理，未來管冪推進期間也將維持高頻率自動監測機制，確保國道及高鐵結構安全無虞。
