Remarks
Indicated VSWR values are also valid for installations on non-metallic surfaces (no specific ground plane requirements). Indicated gain values will be achieved on a metallic ground plane of 1 x 1 m or larger.
High-voltage-protection: no voltage on RF port, if the catenary line touches antenna (EN 50124-1, 27.5 kVAC/1min).
High-current-protection: Designed acc. to UIC 533, DC-grounded antenna element protection against lightning and short circuit with catenary lines (EN50388, EN 50122-1, 40kA/0.1sec)
The above listed parameters are valid for port 1. Port2 meets the following specification:
frequency range 4900 - 5150 MHz, VSWR 1.7, Gain 12.5 dBi
frequency range 5150 - 5470 MHz, VSWR 1.6, Gain 13.0 dBi
frequency range 5470 - 5725 MHz, VSWR 1.6, Gain 13.0 dBi
frequency range 5725 - 5935 MHz, VSWR 1.6, Gain 13.0 dBi
Please refer to the outline drawing to identify port 1 and port 2
