I'd second the comment that you should investigate the rattling/loose parts before you power up again, take the battery off to be extra safe.

As regards the noise, I'd guess the extra noise is simply because a 1/2 wave dipole has a greater capture area than a whip and so is picking up stronger signals and noise. It may also be that your local noise sources have mostly horizontal polarisation and so the dipole is picking up the noise more effectively. If you take the set out to a rural location (once you've fixed the rattle!) and try the different antennas you may find the results are somewhat diffferent.
