Hello:

Thinking about replacing my present random-length antenna which I have
strung around the 4 sides (open loop; 40x25x40x25 approx.) of my attic.

Do listening only. Receiver is grounded to a cold water pipe.

Want omni directional, and wide continual freq. coverage; few hundred KHz up
to 30 MHz.

Depending on what you mean by "... few hundred KHz ...", a large,
indoor, tuneable, rotateable loop antenna may be a good augmentation
to your current, adequate "... random-length antenna ..."
This-a-way, you can rotate to maximize signal reception, or rotate
to minimize interference.

With a little additional "complexity", you might install such a
loop in the attic, as well.
