I had not tried direct to coax yet with the 401. Do have a Matchbox, that comes on line with the Valiant in a couple months.

So, through the middle half of 80/75M, it does pretty good. This is a real possibility for barefoot CW contacts. However, I have gotten quite used to 10 over reports from Europe and the North Atlantic on 3.800Mhz. That needs the tuner. The shack stays pretty warm too...
