 Competitive
Comparison of 2.4GHz Omni-Directional
When designing these antennas, great care was taken
with the radiation patterns, both in the 360 degree
direction and in the elevation plane. (See patterns
below)
Many competitive omni-directional antennas considerably
over claim their gain figures. Very often the radiation
pattern is not smoothly omni but has shallow nulls in
it. In the elevation direction a feature known as "frequency
scan" occurs. This is where different frequencies
reach maximum gain at different elevation angles. From
the subscribers point of view this shows itself by having
different gain figures at one end of the band as against
the other. For example the antenna might be as much
as 8 dB less gain at the 2.485Ghz end of the band as
against the 2.4Ghz end. Even at the 2.4Ghz end of the
band the gain could be as much as 3dB les than the specs.
claim. All this results in poor system performance and
high bit error rates. |
| Highly
efficient, these aesthetically pleasing wifi antennas
cover 360 degrees are ideal for outdoor pole mounting
applications. These omnidirectional antennas are also
available with a 3-degree downtilt.
These 802.11 compatible antennas are suitable for point
to point links, point to multi point links, ISM, WIFI,
WLAN, MMDS, data/telephony and CCTV. Our panel antennas
are IEEE 802.11 compliant, and wireless LAN system,
Bluetooth, Wimax and wifi system compatible

users.
- Designed for pole mount
but wall mount is possible. The 5dBi omni is
a desktop magnetic mount antenna
- Diameter of pole mount size
2.5 cm to 8.5cm - please specify
- Material of brackets: Galvanised
steel 2mm for maximum strength/weight ratio.
- 8dBi, 10dBi and 13dBi antenna
are designed for outdoor use and the 5dBi omni
is for indoor use.
