Default vert vs dipole gut comparison


"ml" wrote

but don't forget, we all agree that somtimes the dipole will work better
sometimes the vert but the realy trick i wonder about is how many times
will the vert be useful

my guess is prob 50/50 but wasn't sure how 'random' it might all be



To understand the benefits of vertical vs. dipole, one has to look at the
radiation diagram of each antenna at particular height. Vertical has the
lobes, where horizontal dipole has the nulls and vice versa. The other
aspect is the polarization which plays bigger role in close range signals,
long range DX signals have varying polarization after they go through the
path. Then there are varying angles of arriving signal depending on
propagation media.
Another spect is that Vertical has omnidirectional pattern, while dipole has
nulls in the pattern (off the ends).

Depends how the antenna pattern and properties fit the current propagation
mode/situation, that antenna would be better. So one has to look at the
antenna pattern and have idea what propagation angles and polarization we
are looking for. Verticals need good ground/soil/radials/salt water for
better low angle performance.

The answer to which is better: vertical or dipole is - YES, jus' depends
wasaaaap (or down)!
