The AL7020S has two models, one for North America Frequency bands (850/1900 
MHz), and one for European Bands (900/1800 MHz). The following connection 
requirements apply for the AL7020S antenna: 

 

•   The AL7020S is terminated with an MMCX connector, and with 50-ohm impedance 

in the relevant frequencies. 

•   The AL7020S can be connected to any antenna with 50-ohm impedance in the 

relevant frequency bands. 

•   The AL7020S is designed to work on VSWR, up to 3:1 The antenna should meet 

this requirement. 

 
 

 

The Antenna-jack of the AL7020S module is an MMCX type. It has a snap-in 
connection. For the antenna-cable RG178 is recommended.
