Here are some 

approximate

 positions of the main coil.  The 

measurement shown is from the top turn on the main coil to 
the top of the collar.   

75 Meters  5 3/8 inches 

40 Meters  1 7/8 inches 

20 Meters  5/8  inch 

15 Meters   1/4 inch 

10 Meters  1/8 inch 

Due to the variables in any given installation, the position of 
the coil can be different from the dimensions shown above.   
The above assumes that there is a three foot long whip or its 
equivalent connected to the top of the antenna. In other 
words, if you attach a fiberglass CB whip to the antenna, it will 
not tune the same way. 

For added efficiency, a longer whip may be used.  The 
antenna is constructed so that an eight foot whip may be used.   

 

Weathershield removed for 

discussion only.
