FIGURE 2.  THE 8 FOOT HEIGHT PUTS THE ENDS HIGH ENOUGH TO PREVENT RF BURNS

THIS WAS FOR 0000 UTC, CLOSE TO SUNDOWN, FOR A LOW PERIOD OF SOLAR ACTIVITY
SMOOTHED SUNSPOT NUMBER, SSN OF 20.  THE RECEIVING STATIONS WERE ALSO
ASSUMED TO BE USING IDENTICAL INVERTED V DIPOLES.  YOU CAN SEE THAT ALMOST
THE WHOLE STATE OF CALIFORNIA IS COVERED WITH S9 SIGNALS, MINUS ONLY A THIN
SLICE OF LAND NEAR THE MEXICO BORDER IN THE SOUTHEAST PORTION OF THE STATE,
WHERE THE SIGNAL DROPS TO S7.  SIGNALS FROM TEXAS ARE PREDICTED TO BE ONLY
S5 OR LESS IN STRENGTH.  SIGNALS OR THUNDERSTORM STATIC COMING FROM, SAY,
LOUISIANA WOULD BE SEVERAL S UNITS WEAKER THAN SIGNALS FROM CENTRAL TEXAS.
NOW TAKE A LOOK AT FIGURE 1B.  HERE, THE DATE, TIME AND SOLAR CONDITIONS
REMAIN THE SAME, BUT NOW THE ANTENNAS ARE 100 FOOT HIGH FLATTOP DIPOLES.
CALIFORNIA IS STILL BLANKETED WITH S9 SIGNALS, SAVE FOR AN INTERESTING
CRESCENT SHAPED SLICE NEAR LOS ANGELES, WHERE THE SIGNAL DROPS DOWN TO S7.
CLOSE INVESTIGATION OF THIS INTRIGUING DROP IN SIGNAL STRENGTH REVEALS THAT
