KEY BENEFITS
Greater Flexibility
Different connector options upon
request. Small form factor and low
profile. Independent of ground, the
performances are maintained
across design.
Quicker Time-to-Market
Standard antenna eliminates
design fees, redesign cycle time
and minimize risk associated with
a customer solution. Quicker time
to market.
