The 214FM antenna bas
an

of
200 ohms.
The
supplied balun matches the
input to 50 ohms.
If
you are using transmission
linewith a characteristics impedance
other
than
50 ohms
or
200 ohms, a matching device must
be made. Refer to any current Amateur Hand-
book for information
on
constructing a
matching device.
TUNING
NOTE:
The
Driven
and
Parasitic
Elements
are
adjusted
independently
in
the
following
manner:
Parasitic
Elements:
This
antenna
is
pretuned
for
maximum
gain
and
best
radiation
pattern
at
146
MHz.
This
setting
will give
optimum
performance
over
the
entire
144-148
MHz
band.
If
you
wish
to
optimize
the
antenna
for a
frequency
higher
than
146
MHz,
cut¼"
off
of
the
total
element
lengths
for
each
MHz
higher
than
146.
Driven
Element:
SWR
can
be
lowered
to
less
than
1.2:1
at
a
desired
frequency
by
carefully
trimming
the
driven
element. Keep
the
element
symmetrical
by
cutting
the
same
amount
from
each
side.
Typical
SWR
curves
are
shown
in
Figure
3A
and
a
cutting
chart
is
shown
in
Figure
3B.
Each
installation
is
slightly
different,
so
cut
the
driven
element
for
the
lower
SWR
at
your
particular
location
.
Measure
the
SWR
as
close
to
the
antenna
as
you
can
for
accurate
results
.

STACKING
This antenna can be easily stacked for
approximately 3 dB more gain each time the
number of yagi is doubled. Refer to Figure 4
for
stacking and phasing harness cutting
information.
The two phasing lines coming from the two
antennas to the "T" connector can be any odd
multiple of one-quarter wavelength in the 75-
ohm transmission line . See Figure 5.
NOTE: When phasing two antennas , the
Driven Element halves that are connected
directly to the phasing lines should be on the
same side of the array .
The feedline impedance is for 50-ohm coax
(RG-213 / u). For detailedinformation on stacking
more than two yagis, please consult any
current Amateur Handbook.

INSTALLATION
This antenna fits a 2
11
O.D
. mast. A 2
11
O.
D.
gal-
vanizedpipeis recommendedfor a sturdymast.
Mount the
antenna
in
the
clear. Surrounding
objects-particularly power lines and
other
ob-
jects
of
considerable mass
or
length-are
detrimental
to
the
performance
of
the antenna.
WARNING
Do
not
allow any part
of
the antenna to
touch power lines. This could cause severe
bums
or
fatal injuries.
When mounting
the
214FM with an
HF
beam
antenna
on
the
same
mast,
the
214FM should
be
on
top.
If
the
214FM is to
be
vertically
polarized, separation of
the
two antennas
should
be
at
least 2 feet.
If
the
214FM is
to
be
horizontally polarized, separation should
be
at
least6feet.
The
mast,
if
metallic, should never
be
run
com-
pletely through
the
plane
of
the
elements.
Slightly reduced performance will
be
noticed if
a vertically polarized 214FM is mounted
at
the
top
of a metallic mast as shown
in
Figure
1.
Horizontally polarized mountingwill
not
be
af
-
fected.
For
optimum performance with a
vertically polarized 214FM, a wooden mast
should be used, and
the
coax routed past the
reflector
then
dropped
to
the
mast.
The
antenna can
be
mounted either vertically
or
horizontally for
FM
or
SSB/CW operation
respectively. Circular polarization can
be
ob-
tained
by
using two yagis.
For
information
about which polarization
to
use, consult local
Amateurs who
use
the frequencies you desire.
