I've always had fine performance from the cheap wire dipoles. I tried
one of the RS omni-directionals once (looks like an X made of 3'
oblong loops), and was not impressed.


Making these toy-like, table-top and wall mounted antennas to work is as
rewarding as giving lessons to teach a baboon the fine art of French
cuisine. Compared to an outdoor, roof-top well-designed yagis with
rotor, these mini-omnidirectionals are like pinworms contending with
anacondas.


Go DXing !


When Sporadic E happens almost anything will give you a catch. There's
nothing wrong with a folded dipole tacked to an outside wall, especially
in a higher-up room or apartment, if that's all you can do.

The average Metro-Area {Local} FM Radio Listener
does not buy and use a "Turnstile" Omni-Directional
FM Antenna for FM Radio DXing. {Distant Listening}.

They buy and use a "Turnstile" FM Antenna because it does
work very well in Urban Areas; where they have strong FM
Signals coming from many FM Radio Stations who's signals
are originating from several locations and directions that
are spread-out all around their Home or Office.

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 !!

James


Wouldn't the best omni-directional antenna simply be a whip? All the
others I can think of are going to be steerable.

A whip or a open ring, depending on polarization. Or maybe an Andrew V.

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.
This has been so for at least a couple decades now.

IIRC - Initially like TV the Horizontal Polarization scheme
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.
