Construction of 30/40 Meter MegaHex beam

  
                         coil across 40 meter feed point                                 40 meter feed showing hairpin inductor and current balun
NOTE 130 pound test blue braided fishing line used as truss supports for the spreaders

 
method of attaching elements to spreader                                               another view of element to spreader attachment

                                            element spacers for 40 meter  portion                                                           2 feed points                                                                  
 
MFJ-269 measuring right at feed point of 30 meter section                  MFJ-269 measuring 40 meter at end of 25' coax


home made base for small tower to support the MegaHex

30 meter feed showing 1:1 50 ohm balun, shunt coil,                                                            Mega Hex is up!                               
and Ameritron RCS-4 coax switch                                                               40 meter elements at 48 feet           
RCS-4 controls the switching through the coax feedline                                              30 meter elements at 41 feet    

lowered to 22'                                            tilted - I can get to any point by tilting and rotating

Measurements taken very low to the ground - expected frequency to rise as antenna goes higher (?)
After raising the MegaHex, additional tuning and adjusting was completed
frequency rise noted to be about 40 KC only

CAUTION!

I am using separate feedlines for 30 and 40 meters.
because of this, I can use monoband matching techniques.
DIMENSIONS AND MATCHING
NOT SUITABLE FOR MULTI-BAND - SINGLE FEEDLINE SYSTEMS!
