You need two different antennas: one for shortwave, and one for the

scanner
because of the difference in frequencies.


Not necessarily so.
[snip]
For a receiving antenna to perform satisfactorilly, you need it to be at
least 1/4 wavelength long, and 1/2 wave is even better, but at shortwave
frequencies, this length can get to be considerable, compared to scanner
frequencies, where an antenna only needs to be a few inches long. So the
actual antenna can't be the same for shortwave as for scanners.

[snip]
You definitely need the VHF/UHF antenna designed for its frequency bands but
it's amazing what can be picked up with a very short antenna on SW. Many
radios overload when connected to efficient antennas - too much antenna
picks up too much energy for the radio. Another consideration is
interference from devices in the house or nearby. Your recommendation for
the scanner antenna to be high and in the clear with good co-ax is also a
good recommendation for the SW antenna to minimise local interference. No
harm in connecting the scanner antenna to the SW radio - you may be
pleasantly surprised.

If you have the ideal radio, then, of course, the ideal antenna will make
the ideal combination. But it's a practical world filled with compromises
and trial and error.
