N male to N male extension cable, 20 inch length, 400 grade low loss shielding.

Standard N male connectors on both ends. We recommend this extension cable compared to some others online because this has a special RFC-400 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, 400 shielded cables have less gain loss. 

Made in USA. This cable is American made and manufactured for superior performance and quality control.

We do recommend RokTape to seal all outdoor connection points.

Compare gain loss:
915 MHz application: -0.063 dB (Helium/LoRa device)
WiFi 2.4 GHz application: -0.106 dB (standard home WiFi networking)
WiFi 5 GHz application: -0.175 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 -0.271 dB for 915 MHz, -0.52 dB for 2.4 GHz WiFi, and a whopping -0.99 dBi for 5 GHz WiFi

That means standard RG-58 cables have over 3x 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.
