Whats the best mobile aerial for 27mhz

Gday,

I got a nice 27mhz radio and Im looking for to some serious DX`ing when and
if the Skip is running again.

I will be doing the DX`ing from a high localtion so I guess I wont need
much.

Thinking of running a linear also 100 watts but them power wont mean much
when your in a high location.

Mike

The 'best' would be the good old 9 foot 'stainless steel' whips - 1/4 wave
at 27MHz. Others may disagree, but back 'in the good old days' when 27MHz
was actually tolerable and skip was good & strong, a 9 foot whip on the car
was far better than anything else!

Why do CBers always come down to 'I need a 100W linear'? If you really want
to run high power and talk long distance, why not study and get your ham
licence, then you can run up to 400W legally (if you get the full call or
limited).

And a high location also isn't the 'be all and end all'. When conditions
are good you can get a decent signal long distances using a few watts and a
length of wire! Just concentrate on making sure you have a good
installation, properly tuned radio and antenna, and you will do much better
than many of these power hungry stations. 100W isn't really going to make
that much difference to your signal at the other end, but it could cause you
problems at your end if you start interfering with other nearby services!

Remember, if the atmospheric conditions aren't right, 1000W and a 200 foot
tower won't get you a DX signal! But in the right conditions, 4W on AM can
do just as well as 100W.

Cheers, and happy DXing!

You cant buy the best anymore !!! It was the 9' steal whip from Tandy
with the spring and ball mount

Was that the one that was similar to what was used in the "Smokey and the
Bandit" movies by Burt Reynolds? It was mounted on a "Trans Am' IIRC.
I used to have the 2 piece style untill some one became jealous and made it
a 4 piece antenna. :-((

Fo mobile - I had a look at some EU-Italian made stuff from a Sydney store.

Blue, red, black or yellow coloured base loaded coil with black steel rod
and shall I say classy with a solid build, not the usual HF ugly black whip
mount. $100 but in my view worth it if your vehicle is worth it.

There's a mob called Enhanced Radio Communications here in Melb. that
imports a lot of good US and European stuff. try them out at

A top loaded 2meter tall wip wouldn't be better then a 1/4wave? I would of
thought ortho the length would be good the radiation angle of a 1/4 wave
would make it a runner up. I valued the low angle radiation and left the
stainless steel wipp in at home. Why is the 1/4wave so good?

Simple there is always something lost when you gain something in aerial
design....

For helical whips it's a bit of efficeny for the shortness of an
electrically loaded aerial. At the end of the day the amount of wire on
there is several wavelengths long if you pulled it all off. So mostly it is
lost in the dc ohms of the aerial. Then the radiation pattern is a bit
higher in angle great if your mate is on a hill (works for you on UHF with
repeaters on hills). Also the bandwidth is better on a 1/4 wave stainless as
it is a real 1/4 wave so a better SWR is held over the whole 40 channels (my
experience is the meter really doesn't move much).

It's a fair question as there is a lot of white man's magic in aerial
design.

My fav uses rather thick wire and when unwound runs to about 12-13foot. Also
given it is top loaded not middle or bottom loaded it should have a very low
radiation pattern compared to a 1/4 wave. In theory the 1/4wave should kick
the pants out of a top loaded wipp in the hills let alone it stands over
2meters...Maybe if they are 2meter hills on the other hand..... :)

heheh yes!!

Sounds to me you know the answer your self...

These become bigger issues the lower the freqs you use..
