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.
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.
