wireless telecommunication and antenna as our long run direction
with our professional ability,rigorous attitude and standard of the
line and enthusiasm and constant input of money for R&D.
With combined endeavours of years in this line,ZD has developed its
own "RF passive products","Systemproducts"and the "The system
structure" "Antenna"product line. Taking the advantages of China’s
best supply chain of local industry as a plus, ZD is bracing up to
become an important participator in the feeder antenna and the
field of wireless network optimization equipment both in China and
the outside world.
