1. Check the resonance of the antenna on the 

40 Meter band. The SWR should be  at a 
minimum near 7 MHz or below. 

 
2. To raise the operating frequency cut  small 

lengths such as 

1

/4 

inch lengths from each of 

the four 40 Meter spokes.  Check the 
resonance point again. 

 
Continue the previous steps until the desired 
frequency is reached. 
 

80 METERS 

 
The 2:1 band-with on 80 meters is 
approximately 40KHz. The top capacitance 
spokes are adjusted to change the resonant 
frequency on 80  meters.  Cutting  the  four 
upper  capacitance  spokes will  raise  the 
resonant frequency. Follow the steps below 
for proper tuning. Never cut the 
capacitance spokes on the rounded ends. 
 
1. Check the resonance of the antenna 

on the 80 Meter band with the spokes 
installed.  The SWR should be at a 
minimum near 3.5 MHz. 

 
2. To raise the operating frequency cut 

small lengths such as 

'/4 

inch lengths 

from each of  the four 80 Meter spokes. 
Check the resonance point again. 

 
Continue the previous steps until the desired 
frequency is reached.
