1. INTRODUCTION
The 915MHz Hercules ISM Antenna is a high performance steel thread-mount ISM
antenna for external use on vehicles and outdoor assets worldwide. Omni-directional
high gain across all bands ensures constant reception and transmission. Durable UV
resistant ABS housing is resistant to vandalism and direct attack. At only 29 mm height
it complies with the latest EU height restrictions directives for roof-mounted objects, with
a diameter of 52 mm. Designed to not catch on tree-branches. The antenna can be
mounted on metal structures.
