The UL-1400-T345U is a versatile, Tri-Band, US Cellular and HSDPA/UMTS High Speed Wireless Modem antenna. It measures 4 cm/1.5" OD x 11 cm/4.5" H and is designed to conveniently mount onto any structure, by means of a single 1/4" (6.4 mm) hole.
Its internal radiating structure is self-contained and operates well with or without a ground plane. Therefore, it can be mounted on a non-conductive support, as needed by your application.
Use this product with any Cellular/Mobile telephone, or a high speed modem (such as an AirCard). Various connector options are offered to interface either directly with the device, or to a standard cable adapter. Through the use of an external antenna with your telephone, you will notice an improvement in signal sensitivity (reception) and coverage. Install the external antenna high enough, and you will also increase your phone's line of sight (generally extends phone's range, particularly if a low-loss coaxial cable is used between the phone and the elevated antenna). An example case study can be found here --> Extending Cellular coverage of a mobile home using a passive repeater scheme.
The UL-1400-T345U connects directly into certain High Speed Modem cards, such as the AirCard models 880/881, 875, 860/850, 775, 750 and 550/555. Select the AirCard connector option for these applications.
