Default Dumb question, I know: RE Bevarage antennas

Beverage antennas are very inefficient. This is ok for an HF receiving
antenna, since lowering the efficiency reduces the signal and external
noise by the same amount. The antenna aids receiving by virtue of its
directivity -- signals from the favored direction are enhanced compared
to QRM and noise from other directions.

You can of course transmit with an inefficient antenna. Some commercial
antennas are quite inefficient, but usually have a desirable feature
such as small size or wide bandwidth in exchange. The price you pay is a
weaker signal at the other end of the circuit. Since people often run
much more power than necessary to communicate, the loss in a Beverage or
other low efficiency antenna for transmitting can frequently be
tolerated. It is, of course, a poor choice if you intend to maximize
your signal at the other end.

ARRL Antenna Book says Beverage antennas are strictly for receiving.
Yet, I hear MANY hams report using one, presumably for transceiving.
What gives?
