The active device is not a preamp. It is an impedance converter.

I thought that was clear from my post when I said Hi Z in.
And that is EXACTLY what is required in an "active antenna"
Although I do not own that particular Lowe board, my Lowe HF-150 "whip
preamp" has gain in addition to Z conversion, so I fail to see where the
term preamp does not apply.

No need to be defensive. We're all friends here. We're both correct.
I was hoping to get the less experienced among us to understand a
little better.

A short (i.e. 1/4 wavelength) antenna is always high impedance.
