Hi,

To pick up a 137 MHz signal from wx satellite (POES), are the discone and
quadrifilar helix antennas similar, I mean, they are different in design but
for the rest ?
Are they both omnidirectional and are they both able to change automatically
the elevation and azimuth to the satellite direction without interruption
and without requiring a rotator ? or only the helix provides this capability
?

Thanks in advance

A discone is a wideband, upside down, vertical monopole, essentially. It has
poor coverage at high elevations. It is omniazimuth.

Why would you need a discone? It's chosen for its bandwidth, and you don't
appear to have this as a requirement. Also its fairly good sized, even for the
skeleton ones.
