WTB Series- Standard Performance Antenna

Application of this very antenna is a quite economical and reliable solution under the condition that there are no special requirements for the electrical characteristics of VSWR, Radiation Pattern, side and back lobe levels. These antennas are compliant to ETSI EN300 833 V1.4.1 Class 1.

WTB Series- Low VSWR Standard Performance Antenna

This kind of antenna is able to be used for such transmission course where there are no specific requirements for side and back lobe levels and the purpose of noise reduction is also available. These antennas are compliant to ETSI EN300 833

V1.4.1 Class 1.

WTG Series- High Performance Antenna

A cylindrical shield is added onto antenna reflector in order to lower unnecessary back lode level. This kind of antenna is able to be applied to such transmission course where the condensation of side and back lobe is in necessity and antenna radome is optional. These antennas are compliant to ETSI EN300 833 V1.4.1 Class 2.

WTG Series- Low VSWR High Performance Antenna

The low VSWR feeder is used for high performance antenna so as to lower the noiseof whole transmission line and antenna radome is optional. These antennas are compliant to ETSI EN300 833 V1.4.1 Class 2.

WTJ Series- High XPD Antenna

This kind of antenna is used for SDH microwave transmission course and cross-polar under same frequency band transmission line that has the properties of high XPD and polarized isolation and outstanding F/B Ratio

Microwave Antenna Category



Microwave Antenna Category

WTS Series- Grid Antenna

This kind of antenna takes the feature of stronger wind-load ability compared with panel antenna and is available to frequency band under 2.7GHz

WTQ Series- Omni Directional Antenna

This kind of antenna is used for base station of mobile telecommunication, point to multi-point, MMDS centre station and the radiation field is 360° average distributions.

WTD Series- Sector Directional Antenna

This kind of antenna is used for base station of mobile telecommunication, point to multi-point, MMDS centre station and the radiation field transmits and receives singles based on a certain angular range.



Reflector

It is made of corrosion-proof aluminium plate, which enhances the corrosion-proof ability of

antenna products. The no-model-spiral equipment is controlled by computer, which heighten the

production efficiency and product quality. This very equipment has been conferred as the First

Grade of National Science and Technique Progress Awards. The constructions of 0.3m-3.2m antenna

share integrated configuration and the 4.0m antenna reflector consists of a 4 pieces of panel.

Feeders Both Cassegraind antenna feeder and front-feed flexible waveguide feeder are available. With

the amelioration of technique, more and more new feeders will be worked out.。

Radome It is used for resistance of ice-load and waste stuff heaping. Both fiber glass and high intensity terylene

are available.

Mounting kits Both hanging And platform mounting kits are for option.

Shield

A cylindrical shield is mounted on antenna reflector along its edge which ameliorates the radiation

pattern of parabolic antenna. The absorbing material is lined in inner surface of shield for WTJ

Series-High XPD antenna so as to minimize the unnecessary side and back lobe.
