Hi all
I have a radio shack discone scanner antenna that I use for my scanner.They
advertise this antenna to transmit on 2 meters and 440.Is this so?If it is I
would like to use it on 2 meters untill I get a better ant up.How well do these
work?The one I have does not have the vertical element on top.It does have the
place for one, but it didn't come with it at the time I bought it.Can I get one
for it?Thanks for all replies.

P.S. I'm a new ham just getting started and I'm sure I will need much help.

Hi Rob--

I have a similar one (not RS), and it works fine. VSWR is under 1.5:1 on both
bands. Give it a try.

About as well as a groundplane type antenna.

The vertical element on top--usually loaded with a coil--provides a narrow band
of coverage in the 50 MHz range to add "low-band" FM or Six meters (this is not
a broadband element). It will contribute little or nothing to your antenna's
performance on 145 and 440 MHz.

Radio Shack has a discone antennae in their new catalog that sells for
approximately $50. I own two of these. They are excellent scanner antennas and
will transmit on 6 meters and above. The single whip in the center is for 6m, and
it is tunable. I have it set up in my living room so that I have a switch box so
that my scanner is always on but when I want to use the antennae to transmit I
switch it to my HT. This works great! You don't get near the performance that you
do with a real antennae (such as a beam) but it works well for a backup or as a
temporary.

hi i have one that i use for a secondary antenna, it works well but
not great. i can transmit from 144 all the way up to 1.2 ghz with very
low vswr.

Hi ,
Discone antennas should provide fairly good local coverage but are not
the best omni-directional antenna out there . However considering how broad
banded this antenna is , it yields decent results . The whip you refer to is
for use in the six meter band . But if you ever want to use the antenna for
six meter work , you can order just the whip itself from www.radioshack.com
or your local R/S store . I just checked the website and if you type in the
catalog number (200-043) it will pull the item up on your screen with a
brief description and several options , including a detailed parts list . I
hope this helps and welcome to amateur radio !

Discones are the electrical equivalent of a quarter-wave. No gain.

But it has 'bandwidth'

WA2CEP added his 2 cents:

So does a random length of coax connected to my dummy load. If I mount it
under my house it is both invisible to my neighbors (stealth) and
wide-band. It is low noise when receiving as well.

Jim, knock yourself out. If you stick the same length of coax in an outlet
receptacle, you receiver will also get very quiet after a while. In any
case, the discone is nothing like a dummy load.

Hi Greg,
Discone antenna are the all-dress ,all-service antenna if you like.
i have one here working on 2 repeaters.one on vhf and the other transmetter
is uhf and working great.
this is not a gain antenna but a general coverage.
the antenna i baught is a SIRIO ANTENNA from ITALY model SN1300N
