RP-SMA male to RP-SMA male extension cable, 10 foot length, CFD-240 (LMR-240* alternative) low loss shielding. This is a good option for extending your factory antenna away from an indoor Helium miner or a WiFi router, or adding additional extension to a coax cable that is already connected to your miner or router.
RP-SMA male connector on one end and a RP-SMA female 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. For even less loss, check our 400 grade shielding options.
We do recommend RokTape to seal all outdoor connection points.
Compare gain loss of this cable:
915 MHz application: -0.7 dB (Helium mining/LoRa device)
WiFi 2.4 GHz application: -1.3 dB (standard home WiFi networking)
WiFi 5 GHz application: -1.8 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 -1.6 dB for 915 MHz, -3.0 dB for 2.4 GHz WiFi, and a whopping -5.1 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.
