Does a Hamstick need a counterpoise?
This will work but you will find it has a very narrow bandwidth. Since it is a dipole you don’t need a ground plane or counterpoise. You may find that using an insulated mast will (or at least a few feet at the antenna end) make it easier to tune. A balun at the antenna may also help.
How does an HF antenna work?
Antennas for transmitting skywaves are typically made from horizontal dipoles or bottom-fed loops, both of which emit horizontally polarized waves. For frequencies in the upper HF band, the ground is a better reflector of horizontally polarized waves, and better absorber of power from vertically polarized waves.

What wire is used for HF antenna?
With braided copper cable the electrical HF conduction is fine It is strongly recommended to use insulated antenna wire at all times. When the cable will be used uninsulated, it will work well in the beginning. Over time, the cable will corrode, affecting the outside of the conductor.
