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)

蓮花Emira 420 Sport跑車。（圖／翻攝Lotus網站）Horn antennaLotus再度把輕量化性能做出實際演出，正式推出全新Lotus Emira 420 Sport。這次升級不只是小改款，而是直接把動力與操控全面拉高一階，目標很明確：讓Emira變成更接近賽道等級的公路跑車。
蓮花Emira 420 Sport戰力大幅提升。（圖／翻攝Lotus網站）動力核心依舊是與Mercedes-AMG合作的2.0升渦輪四缸引擎，但輸出已經提升到414匹馬力、500牛頓米扭力（約新台幣1萬6千元級距扭力概念），不僅比標準版多出54匹，也比SE版本再多14匹。Horn antenna搭配八速雙離合變速箱，動力全部傳到後輪，整體反應更直接也更兇猛。

動力採用AMG的2.0升渦輪四缸引擎。（圖／翻攝Lotus網站）性能表現自然跟著升級。官方數據顯示，0到100 km/h加速只要3.9秒，比標準版快了半秒，極速則上看300 km/h。更誇張的是，如果選配輕量化套件，車重可壓到1430公斤，比原本最輕版本再少25公斤，等於一邊減肥一邊增肌，還順便提升下壓力表現。
