External Antennas Abracon External Antennas exhibit low return loss characteristics, high gain, and Low Voltage Standing Ratio (VSWR). These external antennas are linearly polarized and come in a low-profile, small form factor package with an adhesive mount termination style. The external antennas provide multi-band operation, small VSWR, and Fakra type connector. Applications include various technology and telematics operations. The Abracon external antennas operate within a -40°C to 85°C temperature range and with a 10W input power.
