RP-SMA male to N male extension cable, 3-foot length, KSR-240 low loss shielding.
RP-SMA male connector on one end 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 KSR-240 low-loss cable. 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. Compared to standard RG-58 coax, KSR-240 shielded cables have much less gain loss
Compare gain loss of this cable:
915 MHz application: -0.2 dB (Helium mining/LoRa device)
WiFi 2.4 GHz application: -0.3 dB (standard home WiFi networking)
WiFi 5 GHz application: -0.5 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 -0.4 dB for 915 MHz, -0.8 dB for 2.4 GHz WiFi, and -1.3 dB for 5 GHz WiFi
That means standard RG-58 cables at this length have about 2x times as much gain loss as this cable!
