Diamond Antenna CP-6S Operation Instructions

80m, 40m, 20m, 15m, 10m and 6m (3.5, 7/14/21/28-29 and 50MHz)
Six-band Vertical Antenna
CP-6S
Operation Instructions
●Description
1 T h e C P 6 S i s a s i x - b a n d v e r t i c a l
antenna for HF band.
2 Compact, light weighted and very easy
to assemble.
3 It is completely self-supported and
does not need any guy wires.
4 Trap radials could be concentrated on
one direction instead of spreading
them around the antenna. This is
especially convenient if the antenna is
installed on balcony railing or window
side of condominiums and urban
apartments.
5 Since the antenna is direct DC ground
at the feed point, coaxial cable and
transceiver are being protected from
the high voltage caused by lighting.
6 Center frequencies of the antenna are
adjustable in each band simply by
change the length of each radial
element.
7 Top loading structure utilizing capaci-
tive hat enables the antenna to com-
plete with full quarter wave length
antennas in its performance.
8 It is rigid and rugged enough to with-
stand the wind pressure over 90MPH.
9 Mast brackets area adjustable to
accept 1 1/5" to 2 1/3" diameter mast.
10 Feed point section is kept waterproof
by covering it with support pipe.
11 New band plan on 40m and 10m FM
band compatible.

<<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 dan-
gerous accident. Always ask your
friends for help installing the antenna.
3 Don' t drop the antenna, tools and
a t t a c h m e n t w h e n i n s t a l l i n g t h e
antenna in the height. Install the
antenna before assembling it on the
ground.
<<Antenna location>>
1 If the CP6S is located on the roof of a
house or top of a building, look around
t h e r o o f t o s e e i f t h e r e a r e a n y
obstacles such as an electronic wire or
TV antenna. The CP6S 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 charac-
teristics 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 prob-
lem. If VSWR is higher, stop transmit-
ting and check if the parts of the
antenna and coaxial cable are con-
nected. If there are tall buildings or
obstacles or the distance between the
antenna and the ground is short,
VSWR may not be lowered.
※ D i a m o n d A n t e n n a S W R / P O W E R
meter is an insertion type being con-
nected between a transmitter and an
antenna. Transmitting power and
SWR can be measured with very
simple operations. In addition with
those conventional measurement,
PEP (peak envelope power) on SSB
mode can be measured with a PEP
monitor function. With our Diamond' s
wideband and low insertion loss direc-
tional coupler those measurements
can be performed with minimum effect
in transmission line.
<<During transmitting>>
1 Touching the antenna during transmis-
sion may cause to electrify. Pay atten-
tion not to touch the antenna espe-
cially 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 Cor-
poration.
[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 obstacles
a r e t o o c l o s e t o a n t e n n a ,
VSWR is higher and the radia-
t i o n p a t t e r n i s d i s t u r b e d .
Please install the antenna from
the building as far away as
possible.
Check 2:Did you assemble the antenna
correctly? Please read the
instruction again and reconfirm
the assembly.
Check 3: Is the coaxial cable something
wrong? Please check if solder-
ing 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, build-
ing and other antennas.
1 If the CP6S is located on the roof of a
house or top of a building, look around
t h e r o o f t o s e e i f t h e r e a r e a n y
obstacles such as TV antenna or
water reservation tank. The CP6S has
to be located as far away as possible
from those things to obtain its maxi-
mum performance.
2 If the CP6S 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' to 16' ) away from the building wall
depending on structure of the building.
