OMNIDIRECTIONALITY THAT THEY FOUND, SO WELL USE THE AVERAGE BETWEEN THE
MAXIMUM AND MINIMUM HORIZONTAL PEAKS FOR COMPARISON TO THE GROUND PLANE.
MY MODEL SHOWED A FRONT TO SIDE DIRECTIVITY OF ABOUT 4 DB.  PAR HORIZONTAL
OMNI AT 15 FEET ELEVATION OVER TYPICAL REAL GROUND PEAK GAIN IS AT 18,
AVERAGE 4R5 DBI, AT 5 ELEVATION, AVERAGE 2R5 DBI.  PAR HORIZONTAL OMNI AT
25 FEET ELEVATION OVER TYPICAL REAL GROUND PEAK GAIN IS AT 11, AVERAGE 4R9
DBI, AT 5 ELEVATION, AVERAGE 1R4 DBI.  THE GROUND PLANE WITH BASE AT 15

FEET ELEVATION OVER TYPICAL REAL GROUND PEAK GAIN IS AT 11, 1R7 DBI, AT 5,
0R7 DBI.  THE GROUND PLANE WITH BASE AT 25 FEET ELEVATION OVER TYPICAL REAL
GROUND PEAK GAIN IS AT 8, 3R0 DBI, AT 5 DEGREES ELEVATION, 1R9 DBI.  WHAT I
CONCLUDE FROM THIS IS THAT THE HIGHER ANTENNA IS BETTER FOR LONG RANGE
COMMUNICATION FOR EITHER TYPE ANTENNA, WITH MORE DIFFERENCE FOR THE
HORIZONTAL, AS WE MIGHT EXPECT.  BUT NOTE THAT AT EITHER HEIGHT, THE
