A good source of wire
for a dipole is to buy a 250 roll of #14 Stranded at Home
Depot or other building supply.
You can get it by the
foot, but a much better deal to get the whole roll Black or
White.
Too start cut 2 - 34'
pieces for 40M?? You can use PVC pipe fittings to make center
and insulators (also Home Depot).
Don't fall for the
copper coated steel wire sold as antenna wire.? Yes it is
strong!? I snaps up in a mess, trying to go
back in the roll.? It
is really hard to handle.? If you must, it is just Mig Welding
wire, buy a roll at Harbor Freight.
It is cheap and will
work.

When we set up a
single band wire dipole antenna, it needs to be cut to the correct
length.
This optimal length can vary based on wire diameter, insulation if
any, distance to other objects, ...
So it's usually cut a bit too long, and then "tuned" by measuring
the resonant frequency
and then judiciously trimming the ends a bit.??
Though I got by when starting out (no swr meter or network
analyzer) with just a tape measure.
Once set up, you can drive the antenna from your rig without using
a "tuner",
which is a separate piece of gear to match the 50 ohm transceiver
to whatever the antenna happens to be.
