OK so one succeeds in not making the neighbors suspicious in erecting
the vertical radiator portion.
Now how does one explain the process of putting down all those wire
radials? It never occured to me that you also need stealth radials --
or at least put them down stealthfully. 2AM with miner's cap?
Don't forget radials have to be part of the solution.
