◆ Used for out-door application, ZDA’s base station antennas stand out from other competitors due to their relatively small size, light weight and excellent ability against too high or low temperature, strong wind or too much of water or humidity. Antenna redome is manufactured with non-metal containing fiberglass. Because its Expansion coefficient is identical to reflect panel, the combined unit provides very good water proving capability and could be used in all sorts of different environmental and climate conditions.

◆ Each of our antennas is tested for Voltage Standing Wave Ratio (VSWR), intermodulation, and isolation properties before their packing.

◆ All our base station antennas are manufactured by our own and fully satisfy ETS300 and ISO9001 standards.

◆ Base station antenna fabrication adheres to ETS300 standards, while quality control strictly follows ISO9001 standards.

◆ Based on many years of our own testing and customer feed back, our antennas have a life expectance up to 10 years in normal operating conditions.
