We offer two options of thickness of cable for U.FL cables:
1.13mm mini-coaxial cable (50 Ohm): 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, sometimes the tight space requires the use of 1.13mm cable, because it is very thin and flexible: It is not always necessary to use 1.13mm cable, but on occasion it is necessary to use 1.13mm cable, to prevent the U.FL connector from popping off the U.FL jack.
LMR-100-equivalent cable-type: This is a low-loss coax option for U.FL but not for MHF4 or W.FL. LMR100 cable is double-shielded, low-loss and very flexible/easily bendable coax with black jacket. The double-shielding is a major factor in the higher quality of this cable, which translates into lower loss/better performance. Has the same or better signal-loss-per-meter and flexibility as LMR100, and less attenuation (signal loss) than RG174 and RG178. The higher quality of the cable of this antenna translates into lower loss/better performance. Cable is equivalent to LMR-100 in thickness. Since the LMR-100 equivalent coax has lower signal loss: If this cable works for you without the U.FL connectors popping off the jacks, then the thicker one is the better solution. You can use a hot glue gun to secure the jack onto the PCB, in which case, of course, the thicker cable will not be a problem: This is the best way.
We can make special orders of U.FL cables with either LMR-100 equivalent (for lower signal loss) or 1.13mm cable, for better flexibility.
MHF4 cables, and W.FL cables cables can only be made with the very thin coaxes such as 1.13. MHF4 is not compatible with LMR100 and RG178.
U.FL (Ultra-Miniature Coaxial Connector) is part of the UMCC (Ultra Miniature Coax Connectors) series by Hirose Electric Co Ltd. The U.FL series has become a standard in the wireless industry. It provides an extremely small mounting area weight. The series also offers high frequency performance and has a user friendly tactile lock feeling that ensures a reliable connection.
U.FL male right-angle connector mates with U.FL jack/cable-connector U.FL-LP-66, found on mini-PCI wireless cards such as: MikroTik, Ubiquiti, ZigBee radios such as XBee, and Intel PRO: This pigtail enables connection of an external antenna to a mini-PCI wireless card with a female HiRose/U.FL connector U.FL-LP-66 connector.
Data Alliance’s U.FL connectors are precision machined and gold-plated for low loss.
Lead-free and ROHS compliant: Our antenna cable products are ROHS compliant (connectors and cable).
