------------------------------------------------------------------------------------------------------------------ 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ------------------------------------------------------------------------------------------------------------------ The cable is made by Fujikura. The connector uses a Teflon dielectric. Compared to those whose dielectric material is Bakelite (phenolic resin), the SWR is overwhelmingly lower. The connector screws are metric screws. Actual measurement data of SWR and passing loss is attached. Each product is affixed with a serial number, and after production, we measure and manage the SWR (S11) and passing loss (S21) using a VNA (vector network analyzer). The actual measurement results of SWR and passing loss are attached to this product. The SWR graph has frequency on the horizontal axis, and the graph has a wavy shape. The fineness of this wave becomes finer in proportion to the length of the cable. The position of the wave changes depending on the connector, such as the antenna, connected to the cable. Therefore, the SWR value at a particular frequency is affected by the equipment connected to the cable. Therefore, it is important that the value at the top of the wave in the graph is kept low.
