This applies to applications where a "Screwdriver Antenna" is not possible, and you not too cheep (Yah, you know how you are!)
This idea will allow you to have 7-10 (80-6M) different antennas, and whips that can work, on any of the other bands (Lower part of the antenna sets the band, upper part, sets the segment frequency - Using the Quick disconnects to swap the whips)...

• Buy enough, quick disconnects (QD) for all the antennas, base (bottom piece, the normal use); And, enough, for the center piece (Between the fiber glass base and the whip). Otherwise twice as many as normal,
• All the QD, have to be, all the same brand!!!
• Some brands have a QD kit, this is ok for the bottom QD's;  But, you have to get, hole QD sets, for each bands whip section!!!
• Assemble all the antennas and QD's (don't for get to use "GB OX-Gard" or equivalent, on all the threaded pieces),
• A QD at the bottom, and top of the fiber glass, base part (Two QD per upper antenna),
• Adjust SWR roughly and separate the upper whip for length. You want a 1/4 to1/2 inch or so spread between the different upper whips...
• Once mounted on the vehicle, adjust the antennas as normal. Except, adjust to your lowest operating frequencies. Start at 80M.  Stop, once near 3.0 SWR,
• Usually requires cutting,
• Dont forget safety glasses and debering the antenna rod,
• Example: You operated on 3755, 3840, 3908, 3952, and 3988 MHz. Adjust 80M antenna, too 3755 MHz,
• Just get it close, 2-3 SWR (final pruning, will come later),
• Using white electrical tape, mark the whip for that frequency (write small, as it will cover other freq's) that is was tested for each band...
• Continue for each band. But before cutting, see if an existing other bands upper antenna, is all most already the same length (dont cut it thin, save it).
• The 80M and a 40M may have the same size upper antenna piece (length are the same).
• The goal is to have 7-10 different upper antenna rods that are about 1/4 inch different length...

Your whips (and disconnects, inc.) end up looking like this:
____________________________________________________________________________
___________________________________________________________________________
_________________________________________________________________________
_______________________________________________________________________
______________________________________________________________________
____________________________________________________________________A "fill" whip...
___________________________________________________________________
_________________________________________________________________
_______________________________________________________________
_____________________________________________________________

So now that your done. What now?
So you want to talk on, 7290 kHz. Put the 40M bottom section, and the whip marked within the 40M band.  Check where the SWR is low. Shorter whip for higher freq.  So you find that the 40m whip is best for 7220 kHz, so you need a shorter whip, so using the quick disconnects, swap out the upper section for a, 1/4-1/2 inch shorter whip. Recheck SWR. So you find that the 1/2 inch shorter whip is perfect, mark it as 7250-7300 kHz (or whatever Also you can tweak the whip; But, remember the goal is to have, no two whips, the same size.  Also, that "saved" extra whip, can be used as a "fill" whip, if the existing whips are too long or short. Usually, 1/8 to 1/2 inch, differences are enough)....

QD = quick disconnect asmimbly
