This is what you want. Will blow away about any other omni antenna
out
there. Light years ahead of a discone.

Is there any analysis of this antenna on the web that I might look at?

It's just a heavy duty version of a Scantenna, AKA Monitenna, that RS
and I think it was Channel Master sold for years. I have two of them in
the box ready to go. The original is a flimsy antenna that works great.
They just don't hold up in the winter at all. I had a discone on my
tower until recently when the standoff broke in a storm. The
Scantenna/Monitenna in my attic was better on every freq, and it was 30
feet lower. A ground plane made with an SO-239 connector and some coat
hangers will blow a discone away. A total waste of money, unless you
want it as a back up antenna to transmit on....

I guess I've have different experiences than you.

Is it possible that there is a strong signal source close to you that
was desensing your receiver when using the discone and you've created a
"high pass" filter with your tuned 1/4 wave?

LOL, it seems to work the same way connected to all my
scanners/receivers...

That the discone(s) blows is a much better theory..IMO

A ground plane antenna, though, will limit the useful range of frequencies,
won't it? I agree that it could outperform a discone at (and around) its
resonant frequency, but for wideband scanning purposes, how could it
outperform an antenna better optimized for wideband use like a discone?
Like Donald K, I have had very good experiences with a discone. It even
worked well for HF listening with compact wideband receivers that overload
easily with wire antennas.

On the other hand, if one needs a band-specific antenna, a ground plane
would be easier and certainly cheaper.
