We've got this special low-loss RP-SMA male to N male extension cable. The cable is 38 feet long and has an RP-SMA male 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 a standard N male connector on the other end. We recommend this extension cable compared to some others online because this has a special RFC-400 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 an 8 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 cable limits the cable loss factor. RFC-400 is the recommended shielding for a cable of 38 feet in length.
Compare gain loss:
915 MHz application: -1.4 dB (Helium mining/LoRa device)
WiFi 2.4 GHz application: -2.5 dB (standard home WiFi networking)
WiFi 5 GHz application: -3.8 dB (dual band 2.4/5Ghz WiFi to 5 Ghz networks)
Compare this to a cheaper RG-58 shielded cable of the same length- the gain-loss would be -5.4 dB for 915 MHz, -9.8 dB for 2.4 Ghz WiFi, and a whopping -16.4 dB for 5 GHz WiFi
That means standard RG-58 cables have about 4x times as much gain loss as this cable!
