1.Introduction

The Shockwave TLS.20.1F21 is a mechanically robust, waterproof, external antenna

operating at 450-470MHz with 1 meter of low loss CFD-200 and SMA(M) connector. It

has been designed to be used on a Ground Plane. Common applications are, for

instance :

• Public safety

• Smart meters

• Mesh networks

• Transportation

The antenna has greater than 46% efficiency and -2.6dBi peak gain within the

application band on a 30x30 cm ground plane. Stable radiation patterns over low

angles provides consistent gain in the horizontal plane, meaning that it is especially

suitable for mesh networks or hot spots.

A unique indent tab on the base of the antenna allows a wrench to be used to solidly

lock the antenna on top of its mounting location while tightening up the nut beneath

the metal panel. Waterproof O-rings around the bottom base prevent water from

leaking under the antenna.

The TLS.20 antenna is IP67 waterproof and IP69K resistant against high pressure

water jets in commercial cleaning environments, which makes the antenna ideal for

450-470MHz applications in harsh outdoor environments.
