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 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. 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.
