Who makes a good outdoor, omni-directional fm antenna ?

I prefer to use RG6 as the lead in, and I definitely need an
omni-directional antenna.

Radio Shack used to make a dual element, folded dipole outside fm antenna,
but I don't find it on their website.

Thanks for any tips !!

I'll probably get flamed here... but there is really no such thing as a good
omnidirectional FM antenna. None of them have any multipath rejection
whatsoever, and since multipath is most likely what you're trying to
alleviate, you're just as likely as not to end up with just as bad a signal
(stronger, yes, but no less garbled and noisy) as you would have with your
indoor antenna. In fact, a cheap pair of rabbit ears will usually outperform
one of those turnstiles, unless you live in a perfectly flat area with no
surrounding tall structures.

No flames. The radio shack antenna is a turnstile. Basically two folded
dipoles at 90 degrees to each other with cross feed.

A few years ago, I bought a Cambridge Tuner that came with flexible
dipole (wire) antenna. I also bought a Magnum Dynalab - ST-2 FM
Omnidirectional Antenna shown he

http://www.audioadvisor.com/prodinfo.asp?number=MDST2

Guess what, indoor, the flexible dipole beats the ST-2 hands down in
everyway. No contest.

Two weeks later, the APS-13 antenna I have ordered arrived.

http://www.antennaperformance.com/


Then went to Fry's and bought a rotor with wire-dial control, a
pole (2) and RG6 cable (I'm sure) at high-end store. Then installed
them on the roof by fastening on the chimney and came down to listen.

If there is such thing as miracle on the roof, THIS is IT.

I caught so many stations that I begun to loose count after 105.
I first started listing them one at the time earnestly for the next 4 or 5
days, and then got tired. If I turn the antenna's rotor using the control
at, say, 180 degrees, I'd get an altogether different station -- in the
same dial! They're all clear except when it's overcast. The stations
that comes clear nearby, comes clearer. I get stations from as far as
75 to 100 miles and perhaps farther than I care to know. I dreaded it
each time I came accross and saw this (unfinished) list 'cause I feel
guilty. I really don't wanna do that anymore.

Yes Telamon,

The Turnstile FM Antenna does work very well in Urban
Areas; where you have strong FM Signals coming from
many FM Radio Stations who's signals are originating
from several locations and directions spread-out all
around your Home or Office.

"Turnstile" Omni-Directional FM Antenna (FMSS)
http://www.mindspring.com/~brucec/turnstil.gif
http://www.solidsignal.com/prod_display.asp?prod=FMSS

Mounting the Turnstile FM Antenna Up-in-the-Air
at least 6 Feet about the Roof.

Use RG-6 Quad-Shield Coax Cable for the feed-in-line.

The more complex and expensive alternative would
be a directional FM Antenna with a Rotor.

YOU !

Most FM radio transmitters have vertically oriented radiation
due to the fact that most "home" radio's receive their signal
from "cable" While the only "out of the air" receivers are
table-top transistors or car radios that do have a vertical
antenna. ( afaik in Europe )

Therefo

2 pcs of 75cm ( 3ft ) each rigid copper water-tube.
1 pcs wood or other isolating material of appx. 20 x 10 x 2cm
( 8 x 4 x 6/8 " )

screw the two copper tubes to the wood with 1cm ( 1/2" )
distance from each other.

Connect a 75 Ohm coax, inner conductor to the top and shield
to the lower one, to the copper pipes at the gap you created
in the middle. ( soldering is best )

Now make 3 turns in the coax cable next to the connection with
4cm ( 1.5 " ) diameter.
Fixate it with tape or ty-wraps and mount it on the wood.

Mount the antenna on the roof in a way that it holds some distance
from a pole or wall and that the upper pipe ( the one connected to
the inner conductor of the coax cable ) will be above that same
pole or wall.

CP FM has inherent multipath rejection. I have a 4 element slightly

stations from all around, but I can get virtually every FM station in
Los Angeles and San Diego quite nicely.

Without a doubt, a good Yagi on a rotator is best. I wonder
what the cheapest rotator is these days ?

Tandy quit making their rotatable outside RV antenna. It was not
sold at Radio Shack. Radio Shack does have a similar looking round unit
that does not have the motor.
The thing that might be nice is like the old antennas
that used a multiple transmission line going to a box that selected
element pairs for directional control. You can also do this using two
antennas. I bought an RCA unit that went bust. Its an amplified
little square box I lay on the roof. Works pretty well.

I remember my grandparents had different TV antennas and knife switches
for different channels.

Let the FCC computer make the list for you. Get your latitude/longitude
in Degrees/Minutes/Seconds notation and go to the FCC web site
(www.fcc.gov), link to the Media Bureau section and find the license
database search page for FM. (They have ones for TV and AM, too).

Enter in your location and the maximum distance, and the search page
will give you a list of the stations (in a bunch of different formats).
The lists give the bearing and distance to each station from your
location.

When Sporadic E happens almost anything will give you a catch. There's

RG,

Here are Five Good Omni-Directional FM Antennas :

1 - Indoors the Whip Antenna built into the Radio is
a very good Omni-Directional FM Radio Antenna.

2 - The common FM Folded Dipole mounted Vertically
On-a-Wall is a very good Omni-Directional FM Antenna.
Ready-Made and Low Cost plus Good Perfromance

3 - A single 96" long piece of Wire going Up-the-Wall
from the Floor to the Ceiling that is Tapped at 32" from
the Floor with TV 300 Ohm Twin-Lead to the FM Receiver
can be a very effective Omni-Directional FM Antenna*.

| - 1/2 WL ~ 64 Inches
|
|
|
|
|
================= Twin-Lead to Radio
|
|
| - 1/4 WL ~ 32 Inches

* Also the Single Wire can be replaced by 300 Ohm
Twin Lead too.

That Something Extra : This Flood-to-Ceiling Antenna can
be used a 'bad' Weather In-Doors Shortwave Antenna too.

4 - Simple FM Radio Band Loop Antenna can be used
as a Horizontal FM Loop Antenna and is fairly Omni-
Directional Antenna too.
http://groups.google.com/group/rec.r...5d513ceb21150d
-Or- Mount it Vertically and it is very Directional.

5 - For Out-Side consider the "Snake" [Mono-Pole]
Vertical Antenna for the FM Radio Band

Problem with whips is that they have vertical polarization. FM is always
transmitted with a strong horizontal component, the vertical component is
optional.

Not true. FM is transmitted almost universally as circular polarization.

was great for the Visual Line-of-Sight broadcasting from
the TV Station's Tower to Home TV and FM Radio.

But FM Radios problem was the Automobile and getting
a good quality FM Radio signal to the Cars and Trucks
which 99.73% of the time had Vertical Whip Antennas.

Circular Polarization allowed FM Radio to be broadcasted
equally well to both Home and Automobile; plus Circular
Polarization did help to eliminate some Multi-path problems.

sort of kind a right - to my ways of think ~ RHF

Not always. There are FM stations with no horizontal pol at all, due to
spacing considerations with TV channel 6.

Not true. FM is transmitted almost universally as circular polarization.
This has been so for at least a couple decades now.

Who makes a good outdoor, omni-directional fm antenna ?

I prefer to use RG6 as the lead in, and I definitely need an omni-directional antenna.

Radio Shack used to make a dual element, folded dipole outside fm antenna, but I don't
find it on their website.

Thanks for any tips !!

If you want to save some money, you can make your own omni. Take two pieces of heavy copper
wire, about 30" each, and extend them in opposite directions. You could also use small
copper pipe or something like that if you don't want to use wire. Take two more and do the
same at 90°. Take about a 20" piece of RG6 or RG59 and connect the two dipoles together.
Your downlead will also be RG6 or RG59, attached across one dipole or the other. Put a
couple of loops, around 10" in diameter, in the downlead near the antenna. I have two of
them in my attic, one on a splitter driving two FM radios. Works great.

A Single (1) Vertical Half-Wave Dipole will do
for a basic FM Omni-Directional Antenna.
http://www.northcountryradio.com/Articles/fmdip.htm
http://www.willus.com/author/antenna.shtml

The basic FM Folded Dipole Antenna made out of
300 Ohm TV Twin Lead that is mounted Vertically
also makes a good Omni-Directional FM Antenna.

Also a Pair of TV Rabbit Ears Fully Extended and
mounted Vertically will make a fair Omni-Directional
FM Antenna.

-ps- a Pair of TV Rabbit Ears is a VHF Dipole Antenna.

FWIW - Most of these simple FM Antennas can be
used Inside the House -or- Outdoors in the Yard.
