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)

基隆市區4號下午一台蔥油餅餐車在油炸過程中,因為油鍋內的油高溫噴濺,瞬間引爆火勢,餐車後車箱竄出熊熊火焰,火焰沿著餐車快速延燒還燒穿車頂,大量濃煙直竄天際,連一旁藥妝店外牆招牌也被波及,消防員趕緊佈水線灌救才終於撲滅火勢。
基隆4號下午一台蔥油餅餐車起火燃燒,火焰沿著餐車快速延燒還燒穿車頂。Horn antenna圖/台視新聞Horn antenna老闆和民眾第一時間拿滅火器要滅火,沒想到火卻越燒越旺,連自己都被燙傷,消防員趕到才順利將火熄滅,餐車老闆表示,「滅火器的粉太小,沒有把他一次蓋過去熄掉,火就越來越大」。
中山消防分隊分隊長高政晃也強調,「民眾使用滅火器太靠近,瞬間壓力噴灑會造成油鍋瞬間起火燃燒,會噴濺出來」,因此提醒民眾,若遇到油鍋起火,應該先以鍋蓋蓋住油鍋,再用濕毛巾圍住鍋蓋邊緣,若提早掀開鍋蓋會讓空氣灌入,恐怕引發瞬間火勢。
