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)
115年國中教育會考於昨日登場,今(17)日是第二天,考科有自然、英語閱讀、英聽,將從早上08:30考到12:30。而就在7點多,已經有不少考生與家長提前來到考場,努力溫習到最後一刻,也有許多學校加油團與後援會,拉布條為學生加油打氣。
有考生心情很平靜,表示相當有自信,自己一定能5A++,英文全對;家長也給孩子鼓勵,希望他不要出錯。
教育部指出,昨日社會科有50多件違規、數學科有77件違規,大多是違規攜帶量角器等器具進考場,且違規情況比去年多,大考中心將會檢討釐清。
