The discone would be better for local amateur VHF communication and
listening to the aviation band. The quadrifilar helix would be better
for receiving the weather satellite. If you can only have one antenna,
you have to choose which applications you're willing to accept reduced
performance with.

OK Roy, I well understood.
I suspected well this purpose due to its vertical polarization. In fact I
was misleaded by the short radials placed at 45 deg on top. But it is common
and that doesn't differ from a ground plan vertical design, excepted it
offers a large bdw....

Thanks

According you 'd it be interested or not at all to select a discone
instead
of the helix ?
There is no advantage of using a discone, or even drawbacks vs. the
helix,
excepted the price ?
