-Note----------------------------------
<<Installing the antenna>>
①
Don’t install on a rainy or windy
day since it is dangerous.
②
Don’t attempt to install the
antenna only by yourself. Installing
the antenna alone on the roof may
lead you dangerous accident.
Always ask your friends for help
installing the antenna.
③
Don’t drop the antenna, tools and
attachment when installing the
antenna in the height. Install the
antenna before assembling it on
the ground.
<<Antenna location>>
①
If the CP8040 is located on the
roof of a house or top of a
building, look around the roof to
see if there are any obstacles
such as an electronic wire or TV
antenna. The CP8040 has to be
located as far away as possible
from those things to obtain its
maximum performance. Installing
the antenna too close to the
building wall may cause bad effect
for electrical characteristics of the
antenna.
②
Don’t install the antenna where is
easily reachable by people.
③
Install the antenna firmly not to fall
down due to the strong wind. Even
if falling down the antenna, locate
the antenna at the safe place
where people and building are not
inflicted injures.
<<Before transmitting>>
①
Transmit after confirming if the
antenna works normally by an
SWR meter. If VSWR is less than
1.5, it is no problem. If VSWR is
higher, stop transmitting and
check if the parts of the antenna
and coaxial cable are connected.
If there are tall buildings or
obstacles or the distance between
the antenna and the ground is
short, VSWR may not be lowered.
※
Diamond Antenna SWR/POWER
meter is an insertion type being
connected between a transmitter
and an antenna. Transmitting
power and SWR can be measured
with very simple operations. In
addition with those conventional
measurements,
PEP
(peak
envelope power) on SSB mode
can be measured with a PEP
monitor
function.
With
our
Diamondís wideband and low
insertion loss directional coupler
those measurements can be
performed withminimum effect in
transmission line.
<<During transmitting>>
①
Touching the antenna during
transmission may cause to
electrify. Pay attention not to touch
the antenna especially for children
if installing on a balcony railing.
<<Rumbling Thunder>>
①
The thunder seems to rumble in
the vicinity, don’t touch the
antenna and coaxial.When you
don’t use the radio, take off
the
cable from the radio.
<<If there is something wrong,
stop transmitting immediately>>
①
Keeping transmitting with high
VSWR may cause the radio to be
damaged.
Stop transmitting immediately and
check the following matters. If it
doesn’t solve the problem, please
ask the dealer or Diamond
Antenna Corporation.
[Condition: If the antenna doesn’t
seem to receive well or propagate
well]
Check 1: Is the antenna too close to
the building wall? If the
obstaclesare too close to
antenna, VSWR is higher
and the radiation pattern is
disturbed. Please install the
antenna from the building
as far away aspossible.
Check 2: Did you assemble the
antenna correctly? Please
read theinstruction again
and reconfirm the assembly.
Check 3: Is the coaxial cable
something wrong? Please
check if soldering the
connector is okay and the
wire breaks by the volt-ohm
meter.
・
Antenna location
Resonate frequency of HF antenna
can change based on location.
Antenna should be mounted away
from tree, building and other antennas.
①
If the CP8040 is located on the
roof of a house or top of a
building, look around the roof to
see if there are any obstacles
such as TV antenna or water
reservation tank. The CP8040 has
to be located as far away as
possible from those things to
obtain its maximum performance.
②
If the CP8040 is installed on a
balcony railing, installing the
antenna too close to the building
wall may cause bad effect for
electrical characteristics of the
antenna. Locate at least 2m to 5m
(7
ʼ
to 16’) away from the building
wall depending on structure of the
building.
<<Note>>
・
Fastening the radial element trap
coil
assembly tightly may be
damaged.
・
Install radial as much as far from
building.
・
In case of using the metallic stay
wire,
set the wire on the lower
mast bracket
set and attach the
insulators at within
1m from the
mast bracket set in order
to
insulate.
・
It is possible to remove the radials
you
don’t use the band for.

Assembly Instruction
①
Put radial element in each radial
element trap coil assembly by
referring to the typical element
length listed in Table A/B and
fasten it with element fastener
ring. (Figure-5)
②
Set grip nut rightly to treaded part
of each radial element trap coil
assembly.
③
Connect vertical element parts
(Pipe No. 1, No. 2, S trap, Loading
coil for MHz, Pipe No. 3, No.4, No.
5) and fasten them with tapping
screws and inner tooth washers
by aligning holes in each joint
section.
④
Attach two Hat and two Hat S
alternately on Hat ring.
