Can't speak for the HF side, but 144 sigs are very much attenuated with
trees. There is a tremendous change in signal levels between winter and
summer when the vegetation is on the limbs. Of course, 440 sigs are
even worse. In northern CA, when you drive into the wooded areas, it is
like disconnecting the antenna.
