Yes, that's true. But so will almost any practical antenna. Antennas fed
with open wire line are also generally bad for receive noise because it
is not practical to choke them.

Most of the comments have assumed that your son has adequate space for
a vertical.
I have seen many terrible, limited space vertical installations, where
the antenna is no more than a few feet from the house or other large
structure. These always perform poorly, especially so on the low bands.
Tell us more about what your son has available for space.
Yes, exactly why I posted links to the applications notes -- to provide
some technical background so that he can look around and evaluate the
possibilities.
