If that is not time-nutty, I do not know what will :)
if you're a "real time-nut" you drill your own holes - you buy a surplus
drilling rig, refurbish it, figure out how to work it (maybe there's a
"drill-nuts" list?), etc.
But at least the station will probably fit in your backyard.

for geodetic measurements, they drill a hole down to bedrock, and run a
pipe down to anchor the antenna to the bedrock.
"All holes shall be drilled straight enough so that PVC casing can be
installed in the top 15.5 ft of each hole, and that the steel pipe can be
freely lowered, not forced, for its entire 35 ft length."
