I'm new to CB, and I wonder if anyone can help me by clearing up a persistent question. I read over and over that 108" is the length of a 1/4 wave antenna, and that a half-wave dipole would be 18 feet long in total. These numbers are consistent with each other, but the 468/f formula I see everywhere suggests that something like 103.2" would be more appropriate for the middle of the CB band. If I've done the calculation correctly, 108" is 1/4 wave at 26 MHz, which is not in the CB band.
So... what am I missing?
Practically speaking, why is 108" the best length for a SS whip, i.e. why add a 6" spring to the 102"? For a vertical dipole, are the elements likely to be closer to 108" or 103"?
Thanks!
