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....

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.

I have one of these, and while I'm not expert, it does a wonderful job for
me. I've never used a discone, so I have no way to compare the two...
However, you can buy this antenna from other sources for HALF (or a little
more than half) the price they want at the site that was originally linked

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

Too bad the ST-2 omits the milair freqs :~( I almost ordered one till I
read a DETAILED frequency coverage (30-50, 148-174, 440-470, 470-512,
800-912 MHz) Most stores list it as 30-1300 which isn't quite the same...

Not quite light years ahead of a discone. Last year I put up a discone
on one side of my house and a ST 2 on the other side, fed them both with
RG 6U double shielded. Had them feeding a Yaesu VR 5000 alternately.
The discone was the one that had the vertical element on top.
On 30-50 I could tell no difference between the 2. But I could use
the discone on 6 meter fm with a 1.9-1 swr. on 148-170 they appeared
to be the same. On some freqs the ST 2 was a tad, and I mean a tad
better. ON other signals in VHF (i.e.144mhz ssb amateur) the discone
picked up distant ssb chatter while the ST 2 picked up nothing. On the
discone I can use on 2 mtr. fm with almost a flat swr. On 440-470 they
apeared to be the same for all intent. Although I can use the discone on
440 fm with a 1.5-1 or so swr. On the 470-512 area there is nothing to
listen to around here so thats a wash. But on 800-912mhz the discone
worked quite well and is somewhat resonant there, while the ST 2
seemed to be about deaf in this area. If you live in an area that gets
freezing rain and wind, even the new improved ST 2 will not last. Its
too fragile. I have never had a discone come down. After my tests I took
down the ST 2 and sold it, and still have up the discone. There is no
substitute for being resonant at various points on a freq plot. The ST 2
basically fakes the radio as far as impededance with the 300 ohm
transformer. It hardly blows the discone out of the water, like I hear so
often. Advertising hype.

However it is half the price and includes the feed line and shipping.
It seems by the reports for monitoring the
basics its a appropriate antenna

I havent seen the heavier duty one in person, so I can't say for sure
how strong it is, but a discone really truly blows as an antenna. A
ringo ranger 2 works pretty well, better than any of the discones I have
had on most freqs. I wonder if the Yaesu was hearing better on the
discone because it was desensitizing. I had one here for a while, and it
was a disaster, intermod and hash all over, and so I sold it to a friend
who lives 20 miles from any really big town. Works good out there..

Right now I have two Scantennas in the attic, along with a discone and a
home brew ground plane cut for 161 Mhz (trains), The discone is in the
"sweet spot" in the attic (it was there first), and until I bought the
first Scantenna, I thought it was ok. I even replaced the original coax
on the discone with 9913 and it was a tiny bit better on 800, but wasn't
anywhere else. I have the discone connected to my BC9000, as it's better
on that antenna, since it seems most prone to losing it's cool due to a
nearby TV station's huge signal. The Pro 2005 and 2006 on the scantennas
will both easily beat the 9000 in every way but scan speed, on any
antenna.

If I had my choice as one single antenna to use, I would probably pick
the home built ground plane (I can build one that will last forever),
with the ringo a close second. The scantenna's next only due to it's
fragility. I may build a HD one myself one of these days..

As far as impedance goes, it's pretty meaingless for receivers, loss is
much more of a problem.

I need to find a climber to change the coax on my ringo, and put up
another discone as a backup to it, for 2M/440. I don't want to get
ripped off for 300 bucks like I did 10 years ago, 25 of it was for
coming over the border into my town. That 150 yards cost 4 times as much
as the ground plane I made the day before cost me!
