Description
1.
X-50N/X-50NA employs high performance C-Load struc-
tures.
2.
Newly developed Liner Phase Shifter technology being
employed
on
X-200N/X-300N/X-300NA permite
the
antenna
lOachieve high performance, nìghpower rating-

and broader band coverage
on
both
2m
and
70cm bands.
Each antenna has the following structure:

3.
Newly developed direct element joint structure with !wo
interconnected FRP outershells being employed
in
X-200N/X-300N/X-300NA enables the antenna
to
maintain
the same strength
as
one with one piece structure by its
overlapping FRP outershells. Perfect waterproof being
achieved by ring gasket enables the antenna
to
maintain their performance without awaring rainy
weather. And the antenna
can
be
easily assembled or
disassembled when it·ls required, by tightening or
loosening 'the joint bracket accordingly.

Professional quality maximum wind resistance is achieved

structure avoids awaring for unstable vswrbeing caused by
climatic effects. Rust
and
corrosion free structure, again,
permits the antennas to
be
installed
at
seaside or contami-
nated air environment without any precautions.
5.
Both of the bands,
2m
and
70cm,
can
be operated
simultaneously by using optional antenna duplexer.
• DIAMOND's genuine duplexers are recommended .
6.
DC
ground structure, which escapes high voltage caused by
thunder lightning to the ground, protects your radio
equipments.
Adjustment
Ali X series antennas are completely adjustment free. if vswr
of a antenna
is
extraordinary high, see if each connecting
part
is
well contacted.
It
is
most likely due to bad contact
in
coaxial cable and/or connector connection, or soldering prob-
lem.
Be
sure
to
use 500hms coaxial cable to feed the antenna.
Assembling
the
X-30A 1X-50N 1X-50NA
1 . Attach three radiai elements
to
the feedpoint section, which
is
one piece structure with FRP element outer shell,

Fix support pipe
to
the feedpoint section with a lock screw
by aligning the holes
at
the bottom of the section
and
