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. 二.About packaging. We use a long envelope style bubble film packaging, which is safe, drop-proof, and will not bend.
