AS ILLUSTRATED WITH EZNEC MODELING, THE BLUE TRACE IN FIGURES 3A AND 3B
SHOW THIS NEW BROADBAND DESIGN HAS HIGHER FRONT TO BACK PERFORMANCE AND
BETTER SWR RESPONSE OVER A SIGNIFICANTLY WIDER FREQUENCY RANGE THAN THE
OLDER VERSION OF THE HEXAGONAL BEAM.  THE FRONT TO BACK PERFORMANCE F/B FOR
THE G3TXQ BROADBAND HEXAGONAL BEAM IS IN EXCESS OF 10 DB OVER THE ENTIRE 20
METER BAND, WHEREAS FOR THE CLASSIC VERSION F/B EXCEEDS 10 DB ONLY IN A
RANGE OF 150 KHZ.  IN ADDITION TO THE IMPROVEMENTS IN SWR AND F/B, THE
BROADBAND MODEL HAS A LITTLE MORE FORWARD GAIN AS SHOWN IN THE EZNEC
AZIMUTH RADIATION PATTERN IN FIGURE 3C.  FINALLY, THE SWEET SPOT FOR DESIGN
IS NOT ONLY BROADER BUT IS CENTERED ON THE LOWEST SWR POINT MAKING IT
EASIER TO OPERATE WITHOUT A TUNER.  PERFORMANCE CHARACTERISTICS AND
COMPARISONS FOR THE OTHER FOUR BANDS ARE SIMILAR TO THOSE FOR 20 METERS.
BUILDING A BROADBAND HEXAGONAL BEAM THE BROAD BAND HEXAGONAL BEAM HAS NOW
BEEN BUILT BY A SIZABLE NUMBER OF HAMS WHO ENTHUSIASTICALLY REPORT ON ITS
ON AIR PERFORMANCE EVEN IN THE PITS OF THE PRESENT SUNSPOT CYCLE.  YOU CAN
