The home of the
fabulous
"ONE MAN
TOWER"
Demand for the OMT
continues - I no longer will build the old style towers but I will
"consider" building the 10m, 12.5m, 15m tower in the new "Super Midi"
style (250mm footprint) for those who do want one.
Those who do not know it
might ask "what's so fabulous about this tower?"
Well - the answer to that
question unfolds as you read through this website.
In particular - when you
follow this link to the next page. http://www.spin.net.au/~aeitower/erecting
It's even on Youtube -

"Ru guo ni
xiang zai tian tang zhao dao shang di ni suo neng de dao shi niao shi
diao jin ni de yian jing li!" (Old Chinese proverb)
Roughly
translated it simply means "Looking for gods in the heavens is a sure
way to get an eye full of bird shit!"
All heavy duty "One Man
Towers" are fully certified to exceed the Australian Standard to the
highest wind category and region category - in fact they exceed the
Standard by a very substantial amount - when you buy and install a
"One Man Tower" you can rest easy. With a 239 kph wind rating on the
15m tower I can safely say they are THE WORLDS STRONGEST SMALL
FOOTPRINT FREE STANDING TOWER!
Many radio hobbyists never
realise they are not operating at full efficiency. They buy a fancy
"all bells and whistles" transceiver worth as much as a new car and
they run a piece of second hand coax to what they think is an
efficient antenna.
Pity thing is that
beautiful new transceiver never realises its true potential because
it is trying to operate through a less than optimised antenna.
Many radio hobbyists think
their antenna is fine so long as it shows a good SWR through a tuner
- their antenna is installed on a tower that is a real pain in the
arse to work on - so the antenna is "tuned" as best they can -
installed and that's it. They are trying to feed a "reactance" and
never know it.
With the "One Man Tower"
you can raise and lower your antenna system quickly safely and easily
with BOTH FEET ON THE GROUND!!
The ease of getting to
your antenna allows you to fine tune your antenna system to the enth
degree.
The proof is in the
pudding - you only have to listen to the people who have "One Man
Towers" to realise just how good your station can sound when you are
running a perfectly adjusted antenna system.
But typically a lot of
hams will continue to run less then optimised antenna systems and
they will try to make up for the poor antenna performance by driving
amplifiers and ruining the enjoyment of others by wiping out large
chunks of bandwidth.
The choice is yours - you
can run the best or you can run with the rest!
We still carry the great
little Australian made 5:1 braking winch at a very competitive price
of AUD$150 inc. GST.
(remember - it is
not only against the law - it is bloody stupid - to use an ordinary
ratchet pawl boat winch for lifting)
Here is a photo of the
trailer mounted demo tower outside the workshop.
There is a growing demand
for trailer mounted towers as more and more hams find it impossible
to erect decent towers because of idiotic local authority
restrictions.
So the alternative of
having a "non permanent" instalation becomes more attractive - just
hitch the portable tower to the family car and take the family to
some nice outdoor location for a weekend of camping/fishing and
portable radio operation. A great way to enjoy the hobby and provide
enjoyment for the whole family instead of being shut away in a musty
little radio shack worrying about causing tvi ..........

Portable.....you bet! Here
are the "old" and the "new" portable towers side by side.

3el Yagi for 20m on the fixed station tower)

heavy duty OMT10 trailer mounted tower in its "travel mode"
.......
And a side and rear
perspective of a trailer mounted OMT10
And finally here it is
with a 13el HF LPDA deployed.
The trend toward these
trailer mounted units is obviously related to the difficulties being
encountered by hams trying to get permits to erect towers in many
local authority areas.
But the PLUS side is the
increasing number of portable stations now setting up decent stations
for contesting.
I must admit that it is a
bit of a thrill when I make DX contacts from my portable station.
Especially when the contacts make very complimentary comments about
signal quality from a "portable station" then are amazed when I tell
them just what the portable station comprises.

A series of pics showing
the new trailer mounted unit of Laurie VK4VCC.
The tower is a Midi12.5
which when trailer mounted gives a working height for the antenna of
13m above ground.
The antenna is a four
element tri-band HF Delta Loop with two full wave loops on 20m - 15m
and 10m.
From the ground to the top
of the antenna is 20m.

new trailer mounted "Midi10" at Alice Springs.
I will add a picture with
his tower sporting the 3el 20m Yagi when he sends me one.
Did you think the OMT was
just for antenna arrays?
Here's a 20m OMT in Canada
mounting a 2.25m wind generator.
........ 
And here is that famous
singing ham at OZ5E in Denmark with his 20m OMT - just a little 5el
15m beam to try it out - then he stuck this 80m monster on it -
scary!
Here is a 25m OMT - what a
fantastic view from the top of this little beauty.
We still carry our
range of work/yard
wear. 100% cotton in long sleeve and short
sleeve shirts, trousers and shorts.
Just click the link to see
the photos.
FINALLY THE NEW "Midi10
and the new Midi12.5" ARE HERE!!!!
you
can see them here
Maybe you came here to
browse through the antenna range.
Delta
Loops - Quads - Yagi and assorted bits, including the engineers
reportwith windloading and specified base pad footings.
I have had several people
ask me if I am in partnership with KVK Antennas.
I am not associated in
any way shape or form with KVK Antennas.
DO YOU WANT THIS TO HAPPEN TO
YOU ????
NO WAY - OF COURSE YOU
DON"T.
SO WHAT ARE YOU WAITING
FOR???
GET A "ONE MAN TOWER"
AND GET RID OF THE WORRY!!!
(Many Amateur Radio
hobbyists are using towers that were never designed for the purpose
that they are being used for. The genuine "One Man Tower" was
designed specifically for use by Amateur Radio hobbyists - it
incorporates more features and adds more safety to the hobby than any
other small footprint tower in the world. Continual research and
development has seen the towers remain as user friendly as possible
while the use of the latest high grade steels of Australian
manufacture ensures structural integrity. Built to a standard - not a
price.)
Australian Enterprise
Industrial is an entity unto itself and is a registered
business.
I have not given any
company/business or person permission to manufacture or market towers
under the registered brand name "One Man Tower".
I am aware that some
copies have been produced - these towers have not been built to
genuine "One Man Tower" specifications - THEY WILL NOT SURVIVE THE
SAME WIND FORCE OF THE GENUINE TOWERS.
