Well a tuned half wave isn't ground dependant, that means a r5 r7 or r8
type of antenna.
I have a 200 foot inverted vee in a 112 foot lot.
I hair pin the ends back to the house.
The top is at 55 feet. the ends are about 12 foot high.
It works well on 160 through 10 meters with a tuner.
Do you want to work in the states or chase dx?
