25 ft. Antenna Extension Ultra Flex Cable RP-SMA Male to N-Female MPD-400UF Super Flex Black
Ultra flexible low-loss RP-SMA male to N-Female extension cable- this is MPD-400UF shielded. The cable is 25 feet long and can be used to put an extension between an RP-SMA antenna connector on a Wi-Fi USB adapter or PCI card and an outdoor WiFi antenna that has an N-Male connector. It can also be used with Nebra Indoor, Rak, and Bobcat Miners to connect to our outdoor 915 MHz miner antenna.
This cable will make installation around tight corners much easier and allows for repeated bending of the cable without degrading signal strength over time. Super Flex cable has a better bend radius without any additional gain loss vs a standard 400 grade cable,
We recommend this extension cable compared to some others online because this is a special ultra flexible 400 grade low-loss cable. The antenna to which you will connect this to has a gain. Let's say you will be connecting this to a 5.8 dBi gain antenna. As the cable in between the antenna and device gets longer, you will experience gain loss. With lesser grade shielded extension cables, the huge drop in gain will mean much worse performance. Our special low loss cable limits the cable loss factor and preserves the high gain of your antenna.
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: -0.9 dB (Helium mining/LoRa device)
WiFi 2.4 GHz application: -1.6 dB (standard home WiFi networking)
WiFi 5 GHz application: -2.5 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 -3.5 dB for 915 MHz, -6.5 dB for 2.4 GHz WiFi, and a whopping -10.8 dB for 5 GHz WiFi
That means standard RG-58 cables have about 4x 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 400 grade 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.
Why does this cable cost more than other options I see online of the same length?
Cables with a lower grade shielding will cost less because they consume less raw materials and are cheaper to make. This cable is also three times heavier than a CFD-200 grade cable for example, so the shipping cost is higher too- both on import, and for shipment to the end user.
