Hi.
If you have the space for it, a loop antenna will tend to pick up much less
noise than a random wire or dipole. I also found during a Field Day
eexercise where we had an 80 meter Delta Loop and 80/40 meter dipoles that
the 80 meter Delta loop was considerably less prone to hear lightning
crashes, which proved to be a big advantage with typical June conditions in
New York State.
