80m and 40m V TYPE DIPOLE ANTENNA FOR AMATEUR RADIO

HFV 8040

Operation Instructions

To use this antenna properly, read

this instruction thoroughly before

using it, Keep this manual carefully at

hand for later use.

・ Description

①HFV8040 is a reduced type V

dipole antenna for 80m and 40m.

②Compact, light weighted and very

easy to assemble.

③To adjust the frequencies is

possible to change the hats and

places.

④HFV8040

can

3.5-3.8MHz / 7-7.2MHz.

⑤HFV8040 is a V type dipole

antenna (90 degree fixing).

・ Instruction for use

Impedance of HF dipole antenna

could be changed depending on

the

installation

surrounding situation.

It is OK if SWR is less than 1.5.

However, it might be difficult to

make SWR less than 1.5 according

to the situation.

The frequency range of reduced

scale type antenna is restricted.

We recommend using an antenna

tuner together with this product.

SWR might be higher if there are

other antennas or the mast at the

cove of V-dipole antenna.

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

<<Installing the antenna>>

①Don't install on a rainy or windy

day since it is dangerous.

②Don't

attempt

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.

③Don'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>>

①If the HFV8040 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 HFV8040 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.

②Don't install the antenna where is

easily reachable by people.

used

③Install 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>>

place

Transmit after confirming if the

antenna works normally by an SWR

meter.

<<During transmitting>>

Touching

transmission may cause to 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, 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>>

Keeping

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.

Check 1:Is the antenna too close to

the building wall? If the

obstacles are too close to

antenna, VSWR is higher

and the radiation pattern is

disturbed. Please install the

antenna from the building as

far away as possible.

Check 2:Did

you assemble

antenna correctly? Please

read the instruction again

and reconfirm the assembly.

Check 3:Is

the

coaxial

something wrong? Please

check

soldering

wire breaks by the volt-ohm

meter.
