We've got this special low-loss CFD-240 shielded RP-SMA male to N-female extension cable. CFD-240 cables have the same low rate of gain loss as Times Microwave LMR-240 cables, but at a great price. The cable is 10 feet long (~3 meters) and has an RP-SMA connector on one end (which is used to connect to devices such as PCI and USB wireless adapters that have RP-SMA antenna ports on them) and an N-female connector on the other end. We recommend this extension cable compared to some others online because this has a special low-loss cable. What does this mean? The antenna to which you will connect this has a gain. Let's say for example you will be connecting this to a 9 dBi gain antenna. As the cable in between the antenna and adapter gets longer, you will experience cable loss, which is a drop in the signal gain of the antenna. With low quality extension cables, the huge drop in gain will mean a much lesser range. Our special low loss CFD-240 shielded cable limits the cable loss factor. This can also be used with Helium miners to extend an existing antenna or cable further away. Additional Features: - Length: 10 feet - Impedance: 50 OHM - Frequency: 0-6 GHz - Backward compatible with 802.11g and 802.11b WiFi standards - Compatible with many WiFi adapters
