Nextel Communications and Sprint PCS in conjunction with the Ontario Convention Center have proposed the construction of this three sided pylon sign, designed to accent the architecture of the convention center. Located at a highly visible intersection on the convention center's side, this project will house antennas for both carriers as well as an electronic message board for the center. The carrier's equipment is to be located in a subterranean vault constructed of concrete and camouflaged by native and decorative landscaping.
