Discone scanner plans
 
Does anyone know if there are plans for a discone scanner antenna on
the web to build?

Why not purchase one from RS, reverse engineer the simple layout, then
proceed to design one with the improvements that you think will make it
better ?
You will then have something to compare your new creations with to see if
they really are better.

Are discones the "best" all band scanner antenna? SHould they be
mounted high?

I like your idea. I will have to go online and see what a radio shack
costs. I would like to build one better than you could buy one though.

I found one in RS lastweek , a generic discone for 25Mhz-1300Mhz;
costed a hefty 69 bucks. Also check out antennawarehouse.com, Grove's
etc.

How is it made? Do you like it?

I like them.
I see they now include a vertical element, something they didn't do 10 years
ago when I bought mine.
Seems to me thats theres not much room to reasonably improve.
You either make the elements shorter or longer, and/or of a better grade of
material/sturdier construction.
I might add that mine has stood up rather well to 10 years or wear and tear
exposed to the elements on my roof.

Just a thought: put it in your attic instead - and no weather or rust
problems.

Might be true - But its on a 15 ft mast above the roof.
Putting it indoors would be sacrificing considerable height.
I got 10 years + and still counting, so I think the extra 20 ft height is
well worth it.

For my $.02 worth, I had a RS discone and after two years, a 70+ MPH
wind blew it and half of the radials some 500 feet into the woods. If
you don't have these types of winds to contend with, I'd say it was a
great discone, because it was for the time that I had it.

I now have a "Diamond" and am very pleased with it's construction. We
have had 66 MPH winds in the 2 years since it's been up and it has held
firm, on the same 20" post, since then. The ends of the radials are not
crimped at the ends [like the RS that I had] That is where they broke
off from my antenna.

Let me know if you need more info.

I've owned both the RS and diamond discones and agree with you. The RS
is a good discone but it is fairly fragile. I ended up breaking several
elements on it and the only way I could get replacements was to buy
another RS antenna. After that I installed a Diamond and couldn't be
more happy with it. The diamond is well worth the extra money as
compared to the RS, in my opinion.

If you live - as I do - in an area where ice storms, hurricanes, and strong
windstorms are all common, attic-locating an antenna can even make for much
more choice in what you make the antenna out of if you are making a
do-it-yourself one. (A commercial broadcast tower a half-mile away blew down
during a major storm several years ago.)

Valid points.
No matter how you look at it, giving up 20 ft is quite a sacfice for a
monitor.
Ice/wind storms in my location - No hurricanes.

Yes, I admit ripping off the from someone ( I
couldn't tell you who) probably
on this group though. I've been lurking around hear for about 10 years under
various email addresses (always as myself though)
I decided to go undercover, so to speak, just to avoid spam. How many
times have I read, just remove the "no spam"
from the address to respond, so I stole somebodies (Arnold?s) original
idea.

I cannot to address the question regarding the attached article. I
re-skimmed yesterday before posting and vaguely
recall that the author stated reception was decent below the designed lower
frequency. believe he mentions
that the design could be modified to extend the range down.

I'd LOVE to know why the author calls it VHF/UHF,
when it's low-end is 700mhz??

The truth is out there,

but it's not interesting enough for most people.

Don't do it. Discones are broadbanded with almost no gain on any
frequencies. Buy a Scantenna from Grove Enterprises and use a Radio
Shack vhf/fm/uhf tv mast mount preamp.
