Dual-band Magnetic-mount Antennas
The DRM series dual-band magnetic-mount antennas are designed for the mobile antenna marketplace. The DRM 1800 cellular/PCS antenna operates in the 824 to 894 MHz and 1.85 to 1.99 GHz frequencies. The DRM 1900 GSM/DCS antenna operates in the 870 to 960 MHz and 1.71 to 1.88 GHz frequencies. These antennas are designed specifically to enhance performance of the new dual-band cellular telephones. Using a roof-mounted external antenna can increase telephone performance greatly when in-vehicle operation is required. The units can be used in conjunction with hands-free kits. The magnetic base provides for superior attachment strength in all types of environmental conditions.

ISM Ceiling-mount Patch Antenna
The Squint™ series ISM-band patch antenna features a 3.5 dBi dipole-like pattern shape and ceiling-mount design, which provides a low profile for minimum visual impact. The unit provides for reception and transmission in the 2400 to 2500 MHz frequency band. The radiation pattern offers a 55° beamwidth with the maximum directed at 45° from the horizontal plane. Gain at the horizon is 2.5 dBi. The units utilize the unique MicroAir™ air dielectric design, which eliminates losses associated with etched circuit boards and provides higher performance. SWR is 1.5 (max) on 50 W impedance. Size: 4.000" x 4.000" x 0.875". Weight: 0.27 lb.
