In the 790-7125 MHz band, Indicated VSWR values are also valid for installations on non-metallic suraces (no specific ground plane requirements). Indicated gain values will be achieved on a metallic ground plane of 1 x 1 m or larger. Remarks High-voltage-protection: no voltage on RF port, if the catenary line touches the antenna (EN 50124-1, 3.8 kVDC, 27.5 kVAC, 1min). High-current-protection: Designed acc. to UIC 533, DCgrounded antenna element (protection against lightning and short circuit with catenary lines (40kA/0.125s, 70kA/0.05s).
