The brass plate is embedded on top of : a 2.3 metre high concrete pier, 60 cm in : diameter. The concrete pier is anchored to : exposed bedrock using steel re-enforcement : bars to a depth of 3.0 m. The antenna is : attached to the brass forced centered plate : via a 10 cm high anodized aluminum base. : This base provides a constant height : above the brass plate and also permits : the antenna to be referenced to north. : ** File Audited as of 2008-06-23 2.
