SPIDER BEAM Antenna homemade for DX-Pedition by YB6AR
BASIC
Antenna spider beam is basically yagi antenna.
This is not a
log periodic antenna,
differing only slightly in the reflector and director,
while the driver is
almost like the same.
By bending the reflector and director elements are
also in each band
To make the
spider beam antenna
on 20m, 15m,
10m then just
need an arm length
of 5 meters is enough.
To make the 40m
band then takes
at least 10m arms
In one cable feed line we've been able to play
in many bands.
Usually from 5
bands, 3 bands
even mono band
Basically this antenna in a square shape
with equal sides
and we only
need 4 length sleeves
are the same size
anyway.
Suitable for expeditions to the islands even
portable for traveling
and easy for the
raft.
BASIC MATERIAL
Here we only make the material
available, we happen
to have fishing rods measuring 7m, 8m
even 10m long,
actually there are some material that is
discarded or unused but out of the rest of the term
can also be used for
the 10m band, antenna yagi even kind of
Ground Plan.
Total length when packed
only 2 meters
long all the material
in the pipe size of
4 inches unless mounting breaket
Examples of material
Basically this material is very good quality, with
tubing size 1
1/2 "at the base of the arm and the
arm tip size
3/4", it can
both support the cable already wired antenna
elements.
ASSEMBLE
How to tie a very simple
cable element, where
we use a coaxial
cable wrapping leather
1 "plastic air and teflon very well against the
weather.
We cut up the skin
coaxial cable 1
"in order to clamp the cable from the antenna elements on
each band or maybe the other way
We give you a glimpse into consideration the basic
Picture of how binding the
knot stack on
each element of the
antenna band.
We added a little
swivel in order to maintain order not tangled
wires during installation
and also when the
wind hit.
Binder pole and antenna support arm sleeves
Pole and sleeve arm binder
buffer using the antenna
in the split pipe and welded die stacking and are not
afraid to blow
in the wind.
You can do your
own installation of a total of
at least 10-15 kg
with both hands you can do the founding of
the antenna.
You cheer when
the antenna is assembled as you wish and
you can even
dance in the air DX
The beauty of your spider beam and ready to dance in the air with DX’ers
When all are assembled and
then we just wrap the antenna stayed
where the expedition set out for the place
where the default is not too heavy.
By crossing islands for QRV with DX Aceh Group
we are making things so smooth communication
Thank hopefully writing can be beneficial to your friends and your friends like
Expeditionary hobby DX'er
Hope see you again in the air
If you want to get the material can be ordered through Such material
spiderbeam arms, V
dipole and Vertical from 10m to
160m antenna hexlical,
We help design
Now we've
got a lighter antenna
and do not need
a tow truck to install
the antenna ...
