RADILA 5DFB One Side Detachable SWR Specification Measurement Data Adopted by Fujikura Low Loss Amateur Radio Coaxial Cable Set For Fixed Stations

------------------------------------------------------------------------------------------------------------------ 【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. Adopts the popular coaxial cable 5D-FB-LITE made by Fujikura Dia Cable. FB has less attenuation than 2V, so if you are concerned about attenuation, you can expect an improvement. 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. A serial number is affixed to each product, and after production, the SWR (S11) and passing loss (S21) are measured and managed 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.
