RADILA 5D2V Detachment SWR Specification Actual Measurement Adopted by Fujikura Low Loss Amateur Radio Coaxial Cable Set For Fixed Stations (20m)

------------------------------------------------------------------------------------------------------------------ 【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. ------------------------------------------------------------------------------------------------------------------ A coaxial cable assembly suitable for fixed stations. ・The cable is made by Fujikura. We use the popular 5D-2V coaxial cable made by Fujikura Dia Cable. 2V has greater attenuation than 2FB-LITE, but the cable itself is more flexible. Once you bend FB-LITE, it will twist when you try to return it, but 2V will return to its original shape immediately no matter how many times you bend it. In addition, its ability to return even after bending makes it resistant to bending, making it suitable for use in rotators. Fujikura's FB-LITE is a CA wire (aluminum clad wire), but Fujikura's 2V is a solid copper wire. Due to the rising price of copper, the cost of 2V is now higher, and the transaction price of cables is also rising. The connector uses a high quality connector. Phenol resin (Bakelite) and Teflon are generally used as insulators for connectors, but in the 351 MHz band and UHF (430 MHz band) of digital simple radios, the difference is noticeable and Teflon is superior. The performance of a connector cannot be distinguished from its appearance, but can be determined by actually measuring things like SWR. The connectors used in this product have low SWR and low passing loss based on the results of measuring many domestic and overseas connectors. 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.
