- Note ----------------------------------

<<Installing the antenna>>

Don't install on a rainy or windy

day since it is dangerous.

Don't

attempt

install

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.

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>>

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.

Don't install the antenna where is

easily reachable by people.

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>>

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

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

envelope power) on SSB mode

can be measured with a PEP

monitor

function.

With

Diamondís wideband and low

insertion loss directional coupler

those

measurements

performed withminimum effect in

transmission line.

<<During transmitting>>

Touching

the

antenna

transmission

may

cause

electrify. Pay attention not to touch

the antenna especially for children

if installing on a balcony railing.

<<Rumbling Thunder>>

The thunder seems to rumble in

the

vicinity,

antenna and coaxial.When you

don't use the radio, take off the

the

cable from the radio.

<<If there is something wrong,

stop transmitting immediately>>

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

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

connector is okay and the

wire breaks by the volt-ohm

meter.

・Antenna location

Resonate frequency of HF antenna

and

can change based on location.

Antenna should be mounted away

from tree, building and other antennas.

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.

If the CP8040 is installed on a

balcony

(peak

antenna too close to the building

wall may cause bad effect for

electrical characteristics of the

our

antenna. Locate at least 2m to 5m

(7 to 16') away from the building

wall depending on structure of the

can

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

・Assembly Instruction

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)

Set grip nut rightly to treaded part

of each radial element trap coil
