Horn antenna 金鐘影后黑化! 鍾欣凌變臉「毛骨悚然」
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)
據中國國家統計局公布數據顯示,1-7月全國固定資產投資年增1.6%,增速較上半年放緩1.2個百分點;扣除房地產開發投資,同期全國固定資產投資年增速走低1.3個百分點至5.3%。
據《財新》估算,7月當月房地產投資年降幅擴大4.1個百分點至17%,或與房地產銷售持續惡化等因素有關。7月房地產先行指標全面下滑。其中,新建商品房銷售面積、銷售額年降幅分別擴大2.4個、3.3個百分點至7.8%、14.1%;新開工面積、竣工面積分別年減15.4%、29.4%,低於前值6個、27.6個百分點,後者惡化幅度為各項指標中最大;房地產開發企業到位資金降幅擴大6.1個百分點至15.8%。
