RP-SMA male to N male extension cable, 20 foot length, CFD-240 (LMR-240 equivalent) 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.
Compare gain loss of this cable:
915 MHz application: -1.5 dBi (Helium mining/LoRa device)
WiFi 2.4 Ghz application: -2.5 dBi (standard home WiFi networking)
WiFi 5 Ghz application: -3.7 dBi (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 -3.1 dBi for 915 MHz, -5.99 dbi 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.
