Not to mention safty concerns- like those FCC rules for hams in the KW
class- minimum safty standards - and those at 100 FEET, not in front of
your face ! Also, those have rarely had great swr readings when
measured. Most likely a combonation of these concerns-- Jim NN7K

The reasons may be manifold, but I would figure issues of
loss would be found in the soft tissues of the antenna mast (a
hand/arm) or nearby obstructions (skull/torso).

The dual banders would undoubtedly contain components
that were designed to feed or present a Hi-Z antenna, and would thus
face a rather stiff voltage - hence the limits on power.
