I am trying to design a dipole with traps/loading coils for 160-10 m. Can I probably tune 10, 12, 15 M with the same length of wire?
Can I probably tune 17 and 20 meter with the one wire length?
This would save designing/building/ inserting 3 traps.

If you chart out the lengths you will see some multiples of length. 40 and 15 are related..
as are 10 and 20 or 40 and 80.
Simpler antenna would be a fan dipole. one feed point, multiple wires cut to length..
Plus a lot of weight for that many traps.. Think separate antennas.
An 40/80 trap dipole,(because later on even with multiple band beam, 160 /80/40 will still be wire antennas.)
Lots of planning before you start building these antennas..
