KC901S Network Analyzer Calibration for SHF band 1200 - 1300 MHz

KC901S 網路分析儀 校正於 SHF 頻帶 1200 - 1300 MHz ( center= 1250 MHz, span=100MHz )

50 Ohms N connector ( ideal SWR=1.0 )

50 Ohms BNC cnnector ( ideal SWR=1.0 )

75 Ohms BNC connector ( ideal SWR=1.0 )

SWR in SHF band 1200 - 1300 MHz ( center= 1250 MHz, span=100 MHz )

measured with KC901S

Amateur Radio Antenna for Cars " Nagaya HR770 "

業餘無線電 車天線 Nagaya HR770 ( 磁鐵吸附於角鋼上使用 )

SWR in VHF band 142 - 148 MHz ( center= 145 MHz, span=6 MHz )

measured with KC901S

measured with KVE520

SWR in UHF band 426 - 438 MHz ( center= 432 MHz, span=12 MHz )

measured with KC901S

measured with KVE520

經過這次量測，感覺 KVE520 在 VHF 頻帶還可以，但是 UHF 頻帶可能不大好。
