2m/70cm Dual Band High Performance Gain Base Station Antenna
Description
1. Liner Phase Shifter technology
permits the antenna to achieve
high performance, high power rat-
ing low vswr, and broader band
coverage on both 2m and 70cm
bands.
2. Direct element joint structure with
two interconnected FRP outer-
shells. Enables the antenna to
maintain the same strength as one
with one piece structure. The ring
gasket makes the antenna water-
proof, and therefore maintains
performance even in rainy weather.
When required, the antenna can be
easily assembled or disassembled
by adjusting the joint bracket
accordingly.
3. Professional quality maximum
wind resistance is achieved by the
rugged structure. Superior water-
proofing
eliminates
VSWR that might otherwise
happen in climatic weather. This
antenna may also be used in seaside
or contaminated air environments
as it is rust and corrosion free.
4. Both of the bands, 2m and 70cm,
can be operated simultaneously by
using optional antenna duplexer.
5. DC ground structure, which
escapes high voltage caused by
lightning, protects your radio and
equipment.

VSWR Charts
Adjustment
All X-Series antennas are completely
adjustment free. If VSWR of an anten-
na is extraordinarily high, see if each
connecting part is well contacted. It is
most likely due to bad contact in the
coaxial cable and/or connector connec-
tion, or soldering problem. Be sure to
use 50ohm coaxial cable to feed the
antenna.

will tree close to antenna have a efect on antenna
The presence of trees near the Diamond X200A antenna is unlikely to significantly affect its performance. Trees are not conductive, so they do not directly interfere with signal transmission. However, they can cause some attenuation or signal scattering, especially if they are wet. Since the antenna is designed for high performance and broad coverage, minor obstructions like trees may have minimal impact unless they are very close or directly blocking the intended signal path.
