In my case, a 256 ft center fed wire with 75 ft of 450 window line which runs from the antenna feed point all the way to the operating desk.  I use a Guanella 1:1 balun at the desk to go from the feedline balanced to unbalanced for the KAT500.  The coax jumper between the balun and KAT500 is a common mode choke #8232 from The Wireman.

The apex of the antenna is about 55 ft with the ends dropping down to 25 ft or so.  The antenna wire is #12 copper clad steel.

What are you using for an antenna on 160?

I just set my radio to 100 watts and forget it.

That's more power than is suitable for the HF bands. Most FT8/FT4
users work in the range of 25W on the HF bands. I run legal limit with
WSJT modes only on 160M to work EU from my QTH near San Francisco, and
for weak signal work on 6M (meteor scatter, ionospneric scatter,
tropo, multi-hop E-skip).
