The cable is made by Fujikura.
The connector uses a Teflon dielectric, which has an overwhelmingly lower SWR than connectors with a Bakelite (phenolic resin) dielectric.
The connector screws are metric screws.
Actual measurement data of SWR and insertion loss is attached. Each product is labeled with a serial number, and after production, the SWR (S11) and insertion loss (S21) are measured and managed using a VNA (vector network analyzer). This product comes with the actual measurement results of SWR and insertion loss. The horizontal axis of the SWR graph is frequency, and the shape of the graph is wavy. The fineness of this wave becomes finer in proportion to the length of the cable. The position of the wave changes due to the influence of connectors such as antennas connected to the cable. Therefore, the SWR value at a certain frequency is affected by the equipment connected to the cable. Therefore, it is important that the value of the upper end of the graph wave is kept low.
