Driven-rod monument of stainless 3/4" : steel that forms a braced tripod (rods driven : to approx. 30+ foot depth). Antenna mounts on : a removable brass adaptor. Rods were driven : with a Whacker drill, but 'refusal' was not : attained. Soil here is coarse alluvium in the : uppermost few feet, but fine unconsolidated : allumvium below that. An approx. 4' dia. metal : conduit was emplaced around the uppermost 5' : of the monument (below ground) to isolate from : soil motion. Antenna and conduit are covered : by a large hemispherical polycarbonate dome. : Vertical datum is top of a filed notch in : vertical 3/4" rod. 2.
