Sorry never owned either so can't say which is better -- maybe some one else
can help.

Two considerations though -- radiation efficiency and mechanical integrity.
I suspect the radiation efficiency is about the same between the two.

Some offroad vehicle owners might comment on the mechanical integrity as far
as banging into tree branches etc.
102" whips are usually spring mounted so have a certain amount of give to
them.

Maybe a post at rec.radio.cb will find more responses from actual
users.

Also a CB shop will probably have words of wisdom.

What is very clear is that you would fill a hole in my kill file. Bye.

The message is titled 102" mobile antenna. It should ring a bell about

being
a MOBILE. That should ring another bell that makes you think it's for a
vehicle.
Suggestions were expected from people who have had experience with these,

or
can say something about these type of antenna.

Is it that hard to understand?

But ok, I'll explain a little further.
I'm installing a cb radio in my jeep, and I will be in very remote areas,
therefore I considered the full quarter length whip.

Any suggestions on what antenna to get?

Words of possible wisdom at URL:
http://www.olypen.com/craigh/antennab.htm

Discusses merits of SS vs Fiberglass flexing and also which is the better
radiator.

Can't vouch for it --- but seems well thought out.

Good Luck

Telescopic is a very, very bad choice for anything
that bangs into tree branches or is exposed to
moisture, particularly salt water.

I had bad luck with fiberglass whips. The wire inside
was either too small for amateur-level (100W) transmitters
or had a splice or kink in it. I burned the wire in two
inside the fiberglass - black spot on the outside shell
and very intermittent operation.

I have had good luck with the garden-variety, stainless-
steel whips available from CB shops. If they get dinged-
up or bent, it's just a matter of a little pressure with
both hands and a knee to straighten them out. Besides,
the funkier they look, the more off-road you look. And
they can take kilowatts of power.

If you can't find stainless-steel whips locally, order
several (they're cheap here in Phoenix, about $18 each)
and have them UPS'ed over. That way you'll have spares.

Jim, K7JEB

I got a stainless steel 102" whip (one piece) at radio shack, for about $15.
Will see how it works...
Thanks for all the replies and sorry for the multiple replies from my part,
my provider was timing out and I tried a few times...

Later,

Eric

Your initial question was pretty vague..

The steel whip is pretty robust.
I used to run one, with the spring removed so it was resonant on the ham 10
meter band.
Good results worldwide with 25W on sideband.

As I said, watch the short overhangs!
Otherwise, there isn't much to break on them, and no protruding coils to
hang in the brush.

Now, I run a cobra 6000 centerload, and a Diamond SG7900.
A 102" whip isn't practical, on a roof mount. At least not when your roof is
7' off the pavement.
The cobra is mag mounted, so it fails soft, but still, the fall isn't good
for it, or the car.
The 7900 dosen't bend, it breaks. If it didn't have such great gain, I
wouldn't put up with it.

http://www.inchase.org/outflow/event...2/f5Mount.html
This is the 7900 mount.
I had a bit of a surprise with floopyness of the roof metal, but that was
easily solved, once we found the right bit at the hardware store.

The problem with antennas, is that you can't get high gain, omnidirectional,
and reasonable bandwidth, without also picking "large".

Keep the antenna as clear of the vehicle as possible, and make sure that
what it's mounted to, is really grounded. Bumpers sometimes aren't these
days, and few want to dig the hole in the side panel for the old ball mount.
(Side panels aren't what they used to be either!)
