If you think a DC short will reduce noise, why not just put an RF choke
or moderate value resistor across the feedline conductors of a
conventional dipole?

Do folded dipoles have better noise rejection than single wire dipoles. I
was looking at a drawing one day and realized that they are a dc short. I
know loop antennas are very good about noise.

Loop antennas are difficult to install and a folded dipole would be a lot
easier.
