RADILA 8DSFA MP At Both Ends SWR Specification Measurement Data Adopted by Fujikura Low Loss Amateur Radio Coaxial Cable Set For Connection Between

Ships from Japan RADILA is a manufacturer of wireless equipment. ▸Although we are not well known, we have delivered tens of thousands of cable products to customers as a manufacturing contract for a famous wireless manufacturer. ▸In order to meet the demand for high-performance cables, we launched the RADILA brand and began manufacturing and selling original products with an emphasis on performance. ▸RADILA has many engineers who have been involved in defense technology, and RADILA's products are generously infused with defense technology know-how. ▸We deliver high-quality products to everyone in terms of materials, manufacturing technology, and quality control. This is yellowtail. Low SWR specification. ▸SWR is proportional to frequency and becomes an important factor beyond the HF band. ▸In the 145MHz band and above, connector selection is important, and especially in the 430MHz band, the SWR changes greatly depending on the connector selection. ▸For RADILA products, we collect and measure a large number of connectors from Japan and abroad, use the best ones, and independently test how to attach them to cables to derive the best performance. Ultra low loss. ▸Loss is greatly affected by the attenuation rate of the cable as well as the SWR of the connector. ▸ Even at lengths of several meters for mobile applications, the attenuation rate is not a negligible level and is considered a problem. ▸The thickness of the cable has a limit depending on the intended use, so if the thickness is the same, it will be compatible with the type. ▸This product uses SFA, which has the same thickness as FB but has one rank less loss. ▸8D-SFA-LITE manufactured by Fujikura Dia Cable Co., Ltd. has much lower loss than 8D-FB-LITE, and has the same loss performance as 10D-FB, which is extremely low loss. ▸Also, since CA wire (aluminum clad wire) is used for the internal conductor, the electrical performance is maintained while the specific gravity is less than half that of FB, making it lightweight and easy to use. ▸In addition, the outer cover is made of matte black PVC material that is soft and smooth. Actual measurement data attached (SWR and passing loss) ▸ Normally, cable products are inspected only to check continuity and insulation, but with RADILA products, in addition to these, a VNA (vector network analyzer) is used to check SWR, passing loss, Measuring phase, etc. ▸Measurements are performed by 100% inspection, not by sampling. ▸All products are affixed with serial numbers to ensure thorough quality control. The MP connector screws are metric screws. ▸ Regarding screws for M-type connectors, the so-called M-type connectors currently in circulation in Japan include M-type connectors that use metric screws in accordance with the JIS standard, and UHF connectors that use inch screws. There are connectors (such as PL259 and SO239). ▸There is no difference in appearance between the two and it is difficult to tell them apart, but the difference is that when the screws are fitted together, they are tightened all the way. ▸This RADILA product uses an M-type connector with metric screws. ▸【Impedance】 50Ω ▸ [Recommended use] For connecting amateur radio equipment (for connecting radio equipment and SWR meters, power meters, etc., for jumpers), etc. ▸ [Cable] 8D-SFA-LITE (manufactured by Fujikura Diamond Cable) ▸ [Connector 】MP-MP (low SWR product, metric thread) ▸ [Length error] ±1% ▸ [Manufacturer] RADILA ▸ [Accessories] Actual measurement data of SWR and passing loss ▸ *SFA has less attenuation than FB, so be concerned about the attenuation of transmit power If so, you can expect a big improvement. ▸ *FB has less attenuation than 2V, so if you are concerned about transmit power attenuation, you can expect a big improvement. ▸ *8D has less attenuation than 5D, so if you are concerned about transmit power attenuation, you can expect a big improvement. ▸*The connectors we have selected have low SWR and low passing loss based on the results of measuring many domestic and international connectors. ▸ *Serial numbers are affixed to each product, and after production, measurements are taken using a VNA (vector network analyzer) and managed.
