On 160m Tx is relatively easy, achievable. Vertical polarization is good.
The key is to be able to Rx.
Gain is not the target any more, but signal to noise ratio, and directionability.
Sloopers from the top of a tower is a good starting point.

You do know about "good, better, best," don't you? You do know about
efficency, and horizontal and vertical directivity, don't you? The
difference between your antenna and a much better one can easily be >10
dB. Half that csan be the difference between being heard or not on the
other end, and that becomes increasingly true as local noise levels
increase. N6BT has famously said "everything 'works'" while describing
working all continents using a light bulb (carefully decoupled from the
feedline) as his antenna.
The first hundred countries are the easiest (the first 150 if you're
around the Atlantic basin).
