1. INTRODUCTION
The G21 (Generation II) Hercules is a high performance, steel thread-mount, Penta-band
cellular antenna for external use on vehicles and outdoor assets worldwide. Omni-
directional high gain across all bands ensures constant reception and transmission. The
durable UV resistant PC housing is resistant to vandalism and direct attack.
With IP67 and IP69K waterproof rating, the G21 can be screw mounted on vehicles and
outdoor/indoor assets via its extra thick thread. The antenna has a compact dimension
at only 28.5mm in height and 49mm in diameter. The enclosure is designed to not catch
on tree-branches.
Taoglas recommend a minimum cable length of 300mm when used on a ground plane to
achieve an efficiency of greater than 30%.
This antenna can be mounted on metal structures. The G21 is an ideal solution for
cellular external applications where it can operate with or without the ground plane.
