Unipole sign
Unipole (or monopole) sign is an advertising sign (usually billboard) frame structure mounted atop a single steel pole or column.
The Uni-pole is a large-format billboard type[1] placed atop a very high pole. Its effectiveness is enhanced by the fact that this billboard can be seen even from long distances. There are two options when it comes to illumination: this can either be a light box or front-lit for versatility.
Other uses

Unipoles are also used to mark bus stops.[2]
