You might consider an off-centre-fed dipole with appropriate balun and
choke. A dual core balun that gives good cancellation of common mode
currents at the feed point is essential and some folks add another choke on
the ground with ground spike on the house side to drain off residual cmc.
If you are particularly prone to local noise pickup on your long runs of
coax, then another choke at the entry to your house is a good move.
Coverage of 160 to 6 is possible but the baluns and chokes need attention to
cover that range, especially if suspended and running power unless sturdily
supported. Inverted V is easiest. You might not get all the coverage you
want in one wire but you can join another ocfd onto the original to get more
coverage on difficult bands.
The ocfd gives your matching unit an easier time, ie reduced losses.
Running your radio without a linear means you can have a lightweight aerial
with small balun on fibreglass pole.

Subject: [Elecraft] A Good Antenna Length?
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.
