Antenna Cable / Adapter:  U.FL-female To U.FL male extender
  • One end of this cable has a U.FL-male connector, and the other end has a U.FL female connector. 
  • See our other lengths of U.FL to U.FL cables.
  • The length refers to the length of the cable between the connectors (not including the connectors).
Coaxial cable type options for our U.FL cables:
  • 1.13mm mini-coaxial cable (Impedance: 50 Ohms): This is a very thin and flexible cable, with a black jacket. When connecting U.FL connector to a jack on a miniPCI card or board, often the tight space requires the use of 1.13mm cable, because it is very thin and flexible (diameter is 1.13mm). This very thin cable is typically needed in tight spaces inside of enclosures, so that the U.FL connector will snap down on the jack without popping off.  

  • RG174 coax is thicker and has lower signal loss (attenuation) than 1.13mm while also being flexible/easily bendable. RG174 is better quality than 1.13mm and has a black jacket. The higher quality of this cable  translates into lower loss/better performance. This cable is rated for outdoor use and is also suitable for indoor use. Note that LMR-100 coax is too thick in diameter to use with U.FL connectors.

  • 1.32mm coax is double-shielded while also very thin (1.32mm diameter).  
  • 1.37mm coax is another low-loss option. 
  • Special Orders:  Please see this note about options for thickness of the coax, and note that we can make special orders with 1.13mm, RG174, 1.32mm and 1.37mm coax, if you want a lower-loss, thicker cable for the shorter versions of this cable.   Contact us to make a special order. 

Compatibility with wireless protocols and applications:

Our U.FL cables' range of frequency band compatibility (from 0 to 18GHz) and 50 Ohms impedance matching, makes them suitable and compliant for all the above applications.

U.FL Connectors Characteristics 
  • U.FL female has a socket. U.FL female right-angle type is the most common U.FL connector type found on U.FL cables:  95% of U.FL cables have a U.FL female right-angle connector.
  • U.FL male has a pin and is the connector: Male U.FL is the gender that is the "jack" that is embedded directly on to a circuit board on devices such as BlueTooth boards, and ZigBee radios such as XBee, Printed Circuit Boards (PCBs) and internal mini-PCI wireless cards (even though the gender is male, it is the jack U.FL connector.  Hence the male connectors / jacks are very rigid. 
  • The small size of U.FL connectors has made them an excellent fit in Machine-To-Machine (M2M) and IOT (Internet of Things) wireless applications, since they take up very little space in the cramped cases of small devices, such as Bluetooth beacons.
  • Gender Determination: Micro-connectors such as U.FL have gender that is counter to typical RF terminology for gender, in that "jack" is more typically synonymous with "female:" A U.FL jack on a board (PCB) is the male U.FL, and the connector that mates with the jack is the female. 
  • Connecting and disconnecting U.FL connectors from the jack can be difficult to do properly without damaging the U.FL connector or jack.  We offer a U.FL insertion tool to enable you to connect/insert and remove/disconnect easily, without causing any damage to the cable, connector or jack.
  • U.FL connector is also known as Ultra Miniature Coax Connectors (UMCC), and enables attaching an external antenna to a U.FL jack/connector on Printed Circuit Boards (PCBs):  U.FL female mates with a female HiRose/U.FL jack, also known as U.FL-LP-66 jack/connector.

U.FL Connectors' Material composition

  • Male has a silver-plated phosphor bronze made the shell, and a gold-plated brass made contact.
  • Female: The shell and contact of Female U.FL connectors are made of phosphor bronze but are silver, and gold-plated respectively. Female U.FL connectors are the ones used in the termination of antenna cable.
  • U.FL connectors are precision machined.  The gold-plating enables low signal loss.

RoHS 3 and REACH compliant: All of our antenna cables and RF adapters are free of of heavy metals and compliant with RoHS 3 and REACH.

    Exactly what I was looking for

    Posted by Paul Hillman on 11th Feb 2018

    I needed to replace a mini PCIx WiFi/BT board with something newer, but all that was available were 1/2 height boards and the antenna cables wouldn't reach these new board. I could either use an 'extender' board or extension cables. I looked endlessly, finally I was going to build my own extension cables and looked at digiKey, but only found the male ends. DigiKey recommended this company. These work just fine!!!!

    1.5" U.FL used to adapt half height PCIe WiFI card to a full height slot

    Posted by Unknown on 19th Apr 2017

    I needed to extend only one of the two antenna on the half height replacement WiFi card I bought and the 1.5" lead was more than long enough to do that and is doing the job well. I was afraid a change to the cable length might affect WiFi reception, but as far as I can tell the signal is at least as good as it was before.

    I got the thinner 1.13mm variety and it looks a little thinner than the antenna it is extending but that doesn't seem to matter.

    Docked one star simply because once international shipping was included it was rather a pricey solution.

    Saves on installing longer antennas in your laptop

    Posted by Unknown on 22nd Feb 2017

    These work great, though I do wish they had even shorter extensions. I purchased the 1.5" cable but a 1 inch or even .75 inch would have worked better, but still this was a great fix for bridging my newly installed half-height wifi card in my old HP nc8430 to its original antennas after replacing the old full-height card.

    Thank you!

    Upgrade From Half Height to Full Height PCIe Intel WiFi Card

    Posted by Elias Melas on 12th Jan 2016

    This product works perfectly! :-) When upgrading an older laptop's PCIe mini Intel WiFi Card, you need to get a metal adapter for the new half height cards to fit in the older laptop's full height slot. Amazon carries these adapters and just google search half to full height adapter to find them. They are about $4 bucks each. Once WiFi card is installed with the adapter, the half height card is lower than the original full height card, and the WiFi antenna wires from the laptop won't reach. This extension works and gives you the additional space that you need. I purchased 3 - 6 inch extensions since some cards have 2 wires and others have 3. The wires were longer than expected. I wanted 3 inch extensions but they aren't available from data alliance. I think some other site carries a 3 inch version, but I trust data alliance's quality more. I had to wrap the 6 inch wires with electrical tape since they were too long. All in all, if you are looking to upgrade an old wireless n card to wireless ac and bring new life into an older laptop, this solution works perfectly! :-) Thanks for carrying this product! :-)
