RG01261500Q Datasheet, PDF (2/11 Pages) List of Unclassifed Manufacturers – Road Marker Quad Band Cellular Antenna

1. Introduction
Taoglas USA has designed a range of efficient antennas inside US standard raised non reflective
roadmarkers. These are designed for, and installed inside, the low profile “Bott’s dots” that can
to be mounted directly on the pavement and road in the USA.
These antennas exhibit remarkably high efficiencies in such small packages and live in a very
low profile enclosure. They are designed to be mounted directly on the road, pavement or
manhole cover, just like a standard roadmarker.
These antennas have been potted with the epoxy that is traditionally used to secure the
roadmarker itself to the ground. There are no air gaps whatsoever inside the new type approved
roadmarker with antenna, in order to maintain the mechanical integrity. It is presumed that the
standard black epoxy will also be used to install the roadmarker in its final resting place on the
ground.
