Retevis RHD-771 SMA-M Male 36.5cm 144/430Mhz VHF UHF For Retevis RT1 RT3S RT3 RT8 RT81 For TYT MD-380/UV8000D
Attention,please:
Why Retevis showed the VSWR less than 1.5 on the advert, but I measure higher than 1.5?
1.The accuracy of the measuring instrument. The Retevis factory uses professional measuring equipment(very expensive than handheld devices), which is more accurate than ordinary handheld devices.
2.Each antenna has a center frequency point. At this frequency point, the VSWR value is the lowest and the use effect is the best. So try to measure around 144MHz/430MHz.
