The TLS.90 is a mechanically robust, waterproof, external antenna operating at 868 MHz and 915 MHz. It has been designed to be used on a ground plane. The antenna has greater than 60% efficiency and 1.58dBi peak gain at 868 MHz & 64% efficiency and 1.9dBi peak gain at ISM 915 MHz on a 30×30 cm ground plane. Stable radiation patterns over low angles provide a consistent gain in the horizontal plane, meaning that it is especially suitable for mesh networks or hot spots. Typical applications include: Public safety, Smart meters, Mesh networks, and Transportation.
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.90 antenna is IP67 waterproof and IP69K resistant against high-pressure water jets in commercial cleaning environments, which makes the antenna ideal for applications in harsh outdoor environments.
