RP-SMA male to N male extension cable, 6-foot length, CFD-240 (LMR-240* alternative) 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 CFD-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, CFD-240 shielded cables have less gain loss.
We do recommend RokTape to seal all outdoor connection points.
Compare gain loss of this cable:
915 MHz application: -0.4 dB (Helium mining/LoRa device)
WiFi 2.4 GHz application: -0.7 dB (standard home WiFi networking)
WiFi 5 GHz application: -1.1 dB (dual-band 2.4/5 GHz WiFi to 5 GHz networks)
Compare this to a cheaper RG-58 shielded cable of the same length - the gain-loss would be -0.8 dB for 915 MHz, -1.5 dB for 2.4 GHz WiFi, and a whopping -2.5 dB for 5 GHz WiFi
That means standard RG-58 cables have over 2x times as much gain loss as this cable!
If you invested a lot in your antenna, it is worth the extra amount to get a low-loss cable to maximize your antenna performance. This goes double for Helium mining- a higher loss cable means you may be getting less reach with your miner, and therefore mining much less.

Easy install and works as expected. Really liked the fast shipping i received.
Works great, website chat directed me to correct cable for my Helium miner. Will purchase from Rokland again.
Great product at a great price from Rokland with fast delivery. Well done.
