Unipole sign

From Wikipedia, the free encyclopedia

Unipole (or monopole) sign is basically an advertising sign (usually billboard) frame structure mounted atop a single steel pole or column.

Standard size bulletins available in unipole format:
14' high x 48' wide is the most common (about 4 meters hight x 14 meters wide)
10'6 high x 36' wide
10' high x 40' wide

The single pole proved to be a common technical solution that makes a billboard visible alongside highways or roads. Its height is usually about 28' to 40'.
