At a prior home I had a couple of 1200-1500' that heard quite well to the NE
and SE on the real long haul DX. When I extended the 1200 to 2200' it became
a real dog.
Here Ive been content with 500-750' and concentrated more on F/R
attenuation. Even so being in NH Ive rarely had lightning static problems to
the SW thru NW after midnight even with the the broader front lobe.
A 150' run of 5 Slinkys due East was an exceptionately quiet antenna that
accounted for several new countries in the Mid East and beyond and was quite
directional due to the high velocity factor making it appear to be much
longer. It is not an antenna for high conductivity soils but fine for my
granite ledge just below the surface. The steel coils also rusted away after
18 months and after 3 replacements I quit using; painting would have helped
Im sure.

I actually tried this and discovered that any wire beyond
400 feet made no difference whatsoever. This is because
I am on high conductivity ground. YMMV.
