PATTERN, WITH A MAXIMUM GAIN OF 6R5 DBI AT 33.  THE BEST DX PERFORMANCE IS
FOUND AT 21 MHZ, WHERE THE MAXIMUM GAIN OF 8R0 DBI OCCURS AT AN ELEVATION
ANGLE OF ONLY 21.  AT 28 MHZ THE PATTERN HAS A MAJOR LOBE WITH A GAIN OF
5R0 DBI AT 39, AND A MINOR LOBE WITH A GAIN OF 1R1 DBI AT 10.  WHILE THIS
IS NOT PERFECT, THE MINOR LOBE SHOULD OFFER SOME GOOD DX OPPORTUNITIES
CONSIDERING THE RELATIVELY LOW POWER LEVELS THAT ARE OFTEN REQUIRED ON THE
10 METER BAND.  FIGURE 5 SHOWS THE AZIMUTH PATTERNS FOR AN ELEVATION ANGLE

COMMUNICATION.  THE PLOT SCALE IS REFERENCED TO THE MAXIMUM GAIN, 4R9 DBI
AT 1 MHZ.  AS YOU CAN SEE, THE PATTERN FOR 7 MHZ IS VIRTUALLY
OMNIDIRECTIONAL.  THE DIRECTION OF MAXIMUM RADIATION FOR 14 MHZ AND 21 MHZ
