Troy, for 10/15 meters, it's tough to beat a directed array (i.e., a beam).
To that end, you'll get the most bang for your buck from a quad. Period.

If you're looking at a G5RV, look instead at a Skelton Cone. With your
current transmitter/tuner combo, it will go from 10 through 80 meters, and
in fact, naturally resonates somewhere in the 10/12 meter area. I haven't
run any models on it myself, but others have told me that it actually shows
gain on 40 and 75/80 meters. I don't have any e-files on it, but I can
snaily a drawing to you if you can't find any other info on it.

Of course, these are just my own opinions, and are based solely on emperical
performance observations. Your mileage may vary...

Hi there ladies and gents. I have a question that has most likely come up
here before, and I do apologise if this is visiting old ground.

I am a novice limited license holder in Australia and pretty soon I will
have access to the 10-15 and 80M bands. I would like to know what you
consider as being the best all round antenna for my purpose? I have plenty
of room to mount an 80M dipole antenna, although height is a problem. I
can
go up no more than about 50 feet.

I also have a mast and rotator, so a triband yagi is also on the cards.

Just looking for decent ideas here guy's. I know the question is fairly
open ended, but I would like to consider all my options from those who
have
all the best knowledge of what works and what doesn't. To wire or not to
wire? To beam or not to beam? To G5RV??????

I am running a TS-850, an MFJ 989C Tuner running 100W out of the box.

Thanks very much for your time and I really appreciate your response to my
questions.

Warmest regards

Troy,
Before you do anything check what directions will provide
the most enjoyment. From where you in front and beyond Perth
that would gain your attention? Same goes for the Northern
territories or the interior.
You could also take bands above 20 out of
consideration as the 11 year cycle now provides diminishing
returns. So in your particular case there is more to an
antenna selection than say in Europe and the U.S.
A wet noodle will only give you something to chew on
and not the customary ragchew.
Cheers
Art

Hi Mike,

Skeleton Cone????

I presume you mean Discone. Either way, and as a vertical, this would
not work very well to enjoy that "paper gain." If it works at 80M
(which would mean it is roughly 50 feet tall covering 8000 sq feet -
about one large, or two small residential lots) would suggest its best
radiation advantage for 10M is straight up.

Even though Discones (or other broadband antennas) have wide matching
characterisitics, their actual radiation performance varies
considerable over that same span of frequency.

If you expect to find significant gain, you need the discone to be
significantly larger, with a significantly wide cone skirt. In other
words, something on the order of an HF Horn design.

Best all around antenna is a center fed doublet fed with balanced TL such as
transmitting twin lead, ladder line, or open wire line.

Make sure that the sending end of this TL "sees" balanced source.

Mine is 130 ft long fed with 300-Ohm transmitting twin lead. I use it on all
bands 80 thru 10. I have also used it on 6M with my tuner straining to get a
match.

On 40 the theoretical gain over a dipole is said to be 1.8 dB.

If you can only have one antenna, this is your best bet.

73 es gud luck, Jack K9CUN

Your antenna is not round at all. :-)

Thanks heaps to all who have replied so far. It really is nice to see so
many people willing to share the knowledge with those less in the know.

Warmest regards to all, and if anyone want's to make more recommendations,
feel free.

Tarmo,
Or, you could look at it in the opposite way. The
tuner would replace the beam, tower, and rotor at a
net savings of ~probably~ the price of the tuner. I
wonder why people are so 'afraid' of tuners?

OK, how about this:

I was just listening to an EA8 on 20 meters. He was S9 on the tribander, and
S4 on the 75 meter antenna.

Also, why have a no tune transmitter when you have to retune the antenna
tuner when you change frequency.

Well, lets see.
1. No tower, or room for a beam antenna.
2. Hand, wrist, and arm not broken, sprained, strained, or lazy.
3. The 'no tune' transmitter wasn't ~my~ idea. I don't mind
tuning.
4. Simplifies antenna system.
5. Even if I think antennas are beautiful, neighbors don't.
6. Don't really care if 'they' hear me S-9 or S-4, as long
as they hear me. Same for hearing 'them'.
7. Had a tribander. The loop did as well and in some instances
better. (Do have to admit the tribander wasn't up very high.)
8. Don't have to worry about a rotor and everything associated
with
one.
9. And... we're talking about a "best" 'all around antenna'
which
implies not having several.

No ~one~ antenna does everything well, there are always
compromises
in performance vs. simplicity. Some would rather use a tuner
than
have a number of antennas, some won't. I really don't think
it'll
make much difference either way...

Dont forget a balanced feedline radiates along the line. You may have to
deal with this somehow with the Australian Communications Authority's new
radiation guidelines.

If the currents are balanced, most of the photons are
re-absorbed by the free electrons. OTOH, if the currents
inside a coax feedline are not balanced, an unbalanced
feedline radiates along the line.
