There's it's brother the Bicone https://en.wikipedia.org/wiki/Biconical_antenna
It's more difficult to build and has no real advantage over a Discone.
And the Vivaldi Antenna or Tapered Slot Antenna which is directional and not practical below about 700 Mhz. So the short answer is NO.

Listening and SDR hopping. Ended up at N1BPD's KiwiSDR South Dennis, MA.
Near armchair for a while before going off. Great modulation, no dead air, good music.

Pigmeat, I even like the dance mix version of Cherry Bomb. I think she did that to draw the music noobs to her other stuff. If I ever get a station up I'm going to do an All Joan Jett Show.

I thought the cell/mobile sites were connected by fiber/internet and GPS is whole different system. Anyway, about 25 years ago I said "Next time I fly I'm going to be the pilot".    8)
