15 ft. Antenna Extension Ultra Flex Cable RP-SMA Male to N-Male MPD-400UF Super Flex White
Ultra flexible low-loss RP-SMA male to N-male extension cable- this is MPD-400UF shielded. The cable is 15 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-female 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 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: -0.6 dB (Helium mining/LoRa device)
WiFi 2.4 GHz application: -1.1 dB (standard home WiFi networking)
WiFi 5 GHz application: -1.6 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 -2.5 dB for 915 MHz, -4.8 dB for 2.4 GHz WiFi, and a whopping -8.2 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.

I already have (or want to buy) an external antenna for my wireless adapter, and I want an extension cable so I can put my antenna further away from the adapter. How do I know if this is the right extension cable for me?
Check with the maker or seller of your antenna to find out what type of connector it has. As a rule of thumb, you want to get an RP-SMA male to RP-SMA female extension cable when the antenna you have can connect directly to the RP-SMA connector on your wireless adapter if you wanted it to. That would mean your antenna also has an RP-SMA connector, and this would be the right cable for you. If your antenna has another type of connector, meaning it is not possible for you to connect it directly to the RP-SMA connector on your wireless adapter, then please contact us so we can help you locate the right cable for your needs. Additionally, we always recommend to get as close to the length you need as possible. If you are only trying to go 10 feet, don't buy a 30 foot cable as you will have more gain loss.
