The SCR-296 radar intended to provide targeting data to Battery Const. #294 was constructed on the steep southern face of Rugged Island, about 450 feet east of the battery. Installations at the radar site included an antenna tower, a concrete transmitter building and power generation facilities. Access to the transmitter building, and presumably the antenna tower, was via wooden walkways and stairs starting near the AA magazine, climbing over the ridge to the south and then dropping down to the transmitter building.
Today, the transmitter building has been damaged by earth movement and is resting precariously at the top of a cliff. The power facilities could not be positively identified, but an unusual concrete foundation was located in the approximate area. The antenna site was not investigated due to the steep slope.
