So in receiving the AM BCB frequencies in *the united states, a vertical
antenna is 'generally' preferable over a horizontal antenna? The above is
based on having a receiver without any internal antenna.

If an AM BCB receiver has NO internal antenna, then almost ANY
external antenna will improve its AM BCB performance.

The greatest improvement in that performance will be achieved when the
intrinsic E or H gain of the receiving antenna matches that of the
radiated EM wave (in the US, or elsewhere).
