Why do you need a tuner with a well designed fan dipole. The lengths of
each set of wires can be trimmed to allow coax feed.
I have 2 fan dipoles here, one for 20, 15, and 10 and another for 30,
17, and 12 meters. Each fed with a single coax.
Restricting them to 3 bands simplifies the tuning difficulties
associated with interaction. Keeping the wires about 1 foot apart
reduces that interaction.
I do not mix bands that are 3rd harmonic related on the same coax, it
just complicates things - in other words, I do not mix radiators for 80
and 30 on the same coax, the same for radiators for 40 and 15 meters.
The KISS principle applies.

Why not consider a fan dipole. 160, 40, and 17 ?????? Model it on an antenna
program. You're still going to need a tunner .

What antenna lengths are you using on 160M with your KX3 or KXPA100
internal tuner? What is best for 160-6 meters? I like making my own
antennas with wire.
I usually have to give up one band or another cause it just would not tune
up on a certain band.
I have tried to stay with in these guide lines.
