Is the Rat Shack discone any good (i.e.; worth buying at any price)?

It is discontinued...and the price will be coming down even further if
you wait longer...its one of the best antenna's RS ever sold...don't
miss out on its cheap price...they will go fast...

Yes, it is discontinued because they came out with a new one that has
a 23-30 or something like that MHZ spike on the top of it like the
Diamond antennas.
This is a good antenna for scanner usage, I have one about 15' over my
house and can pick up anything I need to. It has a good wide freq
coverage and it a good deal for 40 bucks.

The Scantenna for $40 is a better buy for scanning. Discjones? I spit on
your discjones! My grandmother uses discjones!
Not a bad antenna, but you need to add a CB type verticle to it to
receive low frequencies well. I modified my RS dicone & still wasn't
that happy with it. The main thing is it's not very hardy in high
winds.
I bought a Sireo (sp) that had the verticle already on it. It is much
more strongly built. It seems to do better on low freqs then the
modified RS discone.
I'd recommend that you buy a Sireo or Diamond discone (around $90.00).
Good luck

I used a CB radio bottom loaded mast, which I mounted to the center stud
of the RS Discone. I can't remember exactly how I mounted it. Used
some kind of treaded coupler from the hardware store I think.

Thanks! I will check into a CB antenna, or as previously mentioned, a GM
replacement mast. One other question: What would be the optimum length
for the element to pick up 30-50 MHz? I guess you can tell that i'm not a
whiz on radio, but i just love monitoring and CB as a hobby. Sorry if
these questions are elementary to those of you "in the know". As always,
any help is much appreciated!
Thanks-Christopher
thanks again
I got a used one cheap, and have had it up for a year or so. It's a
perfectly reasonable antenna for general scanning. Lack of "gain" does
not translate to poor performance.

It's not like this makes it cost extra. It's a characteristic of
discones in general.

It works OK on low-band VHF as-is. Of course it isn't as good as my 6
meter, 6 element yagi for low-band DXing. But then again it doesn't
take up all that space on the mast.
>Four, the damn thing was overpriced to begin with.
Yes and no. You can build a discone for $10 to $15 in parts. What's
your time worth? I got my R.S. discone used for $20. Well worth it...

I have a Radio Shack Discone up in the attic feeding to radios
downstairs with quad-shielded 75 ohm coax..... so there!
Real men don't need impedance matching for receive antennas (but that
quad shielding sure makes a difference!).

Well, then...I guess the past decade or so of monitoring for me
has been a total waste of time...<g>
I use a discone for scanning...the "no gain" argument doesn't
hinder me in the least - I live in an area that has plenty
of activity - and I do not require "gain" or "amps" on the
input.
The discone also performs admirably on 220mHz, 2-meter, and 440
for me, too.
SO...the discone from Radio Shack has its place for many.
And their NEW discone promises better low-end coverage.

I have a discone mounted up 40 ft using low loss RG-213, big cable
tough to work with but the price was right, it is the difference between
night and day, to improve lower end reception I adapted a firestick
mobile CB antenna and screwed it on the top. I have heard a tapped out
GM antenna will work also.
I would like to get a directional antenna so I could zoom into certain
signals. I have heard TV antennas mounted vertically do pretty well. Has
anyone tried this and how are you using the 2 antennas, i.e. rf switch
or combiner, also are there ready made baluns from 300 ohms to 50 ohms
impedance.
living off the ether of others, ;)
derick
But it won't STAY in its place as it is too flimsy.
Don
Yeah you could use a TV ant with a rotator. I use a Grove Scanner beam
for the same effect feeding a Diawa CS-4 coax switch (4 BNC inputs/1 BNC
output) as well as a 8ft vertical for low band stuff, and a Diamond
(brand) discone in parallel with a 2in spike for +1000mhz "stuff".
Good Monitoring,
Don :-)

Completely irresponsible of you, Don, to state that. I seriously
doubt you have EVER owned or even had your hands on one of these
antennas --- because mine has survived 60+ MPH winds here in
Southern California with no problems.
have had mine mounted on 2 10' poles strapped to my chimney for 10
years thru noreaster's and countless other storms with no
problems,works great with my 2006, and from western suffolk,long
island can receive all 5 boros (approx. 50-60 miles)Worth the 60 bucks
I paid for it.Just my 2 cents.
-bob-
Saw one in a RS store + reports from others. I wouldn't buy one. I
bought a bunch of Diamond discones when they were cheap(er). 60mph?
That's a pretty stiff wind for here in SoCal.
Good Monitoring,
Don :-)
Clueless wonder. All antennas are reciprocal. (sp) They transmit as well as
they receive. An antenna designed to transmit will also receive on those same
frequencies equally well.

How much is RS clearing out the discone for?

The OLD discone without the top whip is indeed being sold out on
clearance pricing. The NEW replacement discone WITH the top whip is
$59.95.
Steve
$20 off normal, or $39.95.
After seeing the postings, I went to the Radio Shack up north (north Idaho).
The discone was marked $44.95 -- rang up at $39.95. Great deal.

Thnx Jason
Sammy Salesdroid probably does not know or understand the difference
between the OLD discone (without vertical element) and the NEW discone
(with vertical element)
