1. Introduction
Taoglas USA has designed a range of efficient antennas inside US standard raised non-reflective
road markers. These are designed for, and installed inside, the low profile “Bott’s dots” that can
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 road marker.
These antennas have been potted with the epoxy that is traditionally used to secure the road
marker itself to the ground. There are no air gaps whatsoever inside the new type approved
road marker with antenna, in order to maintain the mechanical integrity. It is presumed that the
standard black epoxy will also be used to install the road marker in its final resting place on the
ground.
The CAB.820 cable assembly is included so the antenna cable can be easily disconnected if
desired. This is useful when the antenna is mounted on a manhole cover. If the manhole cover
is lifted, the cable will split at the push-pull connectors, preventing damage to the cable.
