[time-nuts] Best location for a GPS antenna...?

[David McGaw]

Best would be to have a lightning rod in the vicinity of and above the 
antenna.  A sharp-pointed rod does not attract lightning, it REPELS it 
and has a cone of protection under it.  While the effect is not 
understood, it apparently discharges the surrounding air through corona 
discharge - the sharper the better.
