INSTALLATION
SUGGESTIONS
Your Cushcratt\/HF
beam
is
designed
and
manufactured
to
gi
ve
t
op
performance
and
troub
lefree
serv
i
ce
.Theantennawill
perform
asspe
cif
ied,
if
the instructions
a:i
d suggestions are followed, and if
care
is
used in assembly
and
installation.
MAST:
The
antenna may
be
mo
unted
on a
mas
t
diameter
up
to
2 inches (5.1
cm)
.
MOUNTING
:When
:nounting
more
than
one
beam
on
the same mast, theyshould be
mounted
at
least 1
/,
wave-length (of the lower frequency)
away from
other
antennas,
Ge
nerally,
it
is
best
to
mount
these beamsabove tower frequencyaniennas.
LOCATION
:Locationoftheantennais very
important.
Surrounding
objectssuchastrees,
power
lines,
othe
r antennas,
etc
.willseriouslyreduce
efficiency.
To
minimize
the
ettects
of
surrounding
ob
ject
s,
mountthe
antennaas
hig
h andIntheclear
as
possible
.
If
metal
guy
wires
are
used,they
should
be
broken
into
non-re~onant
lengths
with stra
in
Insulators.

ELEMENT
ASSEMBLY:
The
elements
except
for
the
dipole
are
taPE'(I
together.They
are
progressively
shorter
from
reflectorto
directors.Using
fi
gure
1
mount
the longest
element
near the holes
for
theu-bolts. Next
using
figure
2
mount
the
dipole
. Now
mount
t
he
longer of the remaining
elements
next
to
the
dipole
and
then
mount
the
remaining element
at
the
end
of the
boom.
MAST
MOUNT:
The
boom
is
designed
for
either
vertical
or
horizontal polarization. Refer
to
figure
3 and
mount
the
u-bolt
to
the
boom
and mast.
When
verti
cally polarized,
the
Reddi-Match
rod
should
be
pointing
up
.
TUNING:
The R
eddi-Match
is
set
at
the
factory
for
50-ohm
and
center
band
operation
.
If
retuning becomes necessaryuse a
good
qu
alitywatt
meter.
It
is
not
necessary
to
cut
your
feedllne
or
p
rune
It
to
a
particular
length;
any
length
cable
may
be
usedwith
the
beams. However, the
cable
should
be
as
short
as
possible
to
redu
ce
feed
line
losses.
Your
cable
should
be
equ
i
pped
witha standard PL-259
coax
ia
l titting,
to
connect
to
the
Redd
i-
Match,
figure
2.
Tune
the
antenna
at
your
center
frequency
;
using
a
50-ohm
feedl
in
e
from
your
transmitter
,and a
watt
meter.
Connect
the
wa
ttmeter
to
the
antennawi
th
a
short
length
of
50
ohm
coaxialcable.
Set
the
wa
tt
meter
for
reflected
power.
If
therefle
cted
power
ls
high,
loo
sen
thetuning
strap
and
adjust
it
slightly
In
either
direction
. Movea
wa
yf
rom
theantennaand
check
the
reading
.
If
the
reflected
power
Increased,
move
thestrapback
to
its original posit
io
n
and
adjust
in
the
opposite
direction.
If
the
reflected
power
dropped
, repeat
the
adjustment
procedure
until you achieve
minimum
reflected
power
on
the
wa
tt
meter.Disconnectthe
cable
andwatt
meter,
and
tighten
the
tu
ning
strap
secu
re
ly.
Use
the
vinyl
boot
on the
coax
ia
l
cable
to
the
beam
to
Insure a weather
proof
connection.
Coat
the
outside
of
the
alumi
num
connector
threads
and the PL-259'swiththe
sill
cone
grease
provided
.
Do
not
coat
the
connector
center
pin
or
socke
twithsilicone.
Slide
the
vinyl
boot
over
the
connector
and
against
the
brae-
ket
for
a
good
weather
tight
connection
,
figure
2B. Run
the
coaxial feedllne
along
the
boom
and
down
the
mast
using
electrical
tape
to
hold
it
in
posit
io
n.
STACKING
FOR
MORE
GAIN
Two
Econo
my
beams
may
be
stacked
for

IncreaseusingtheP14-VPK
stacking
kit.
The
kit
includesahorizontal
support
boom,
hardware
and RG-59/U
cable
harness.
Four
beams
may
be
s
tacked
w
it
h
two
P14-VPK kits
and
a
