Direct joint structure (X-200N / X-300N/X-300NA)
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- ,Iow vswr,
and broader band coverage on both 2m and 70cm bands.
Each antenna has the following structure:
X-30A 1/2 wave element(2m),
5/8 wave!wo element(70cm)
X-50N 1 NA 6/8 wave C-Load(2m),
5/8 wave three element C-Load(70cm)
X-200N 5/8 wave !wo element(2m),
5/8 wave four element(70cm)
X-300N INA5/8 wave !wo element(2m),
5/8 wave five element(70cm)
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.
4. Professional quality maximum wind resistance is achieved
----by-theirmgged"strocture: And superrorwaterpron
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 1 X-50N 1 X-50NA
1 . Attach three radiai elements to the feedpoint section, which
is one piece structure with FRP element outer shell,

2. Fix two mast brackets to support pipe, Then connect
coaxial cable to the feedpoint section through support pipe.
Fix support pipe to the feedpoint section with a lock screw
by aligning the holes at the bottom of the section and top of
the pipe,
3. Attach assembled antenna to a mast by taking whole
balance into account and fix it firmly as shown in Fig. 1.
