RP-SMA male to N male extension cable, 20-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. 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: -1.5 dB (Helium mining/LoRa device)
WiFi 2.4 GHz application: -2.5 dB (standard home WiFi networking)
WiFi 5 GHz application: -3.7 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 -3.1 dB for 915 MHz, -5.99 dB for 2.4 GHz WiFi, and a whopping -10.2 dBi 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.

Additional Features:
- Length: 6m (20 feet)
- Impedance: 50 OHM
- Frequency: all bands from 0-6 GHz, including 868-915 MHz LoRa, 2400-2700 MHz WiFi/ 5100-5900 MHz WiFi
- Compatible with 802.11ac, 802.11n, 802.11g and 802.11b WiFi standards, as well as LoRa 915 MHz
- Compatible with many WiFi adapters & Helium miners with RP-SMA ports
