4.2.1. SUPPORTEDANTENNA
ThereceiverprovidesaTNC‐typefemaleconnectorforconnectingtoan
antenna.ThereceiverisintendedforusewithaCHCGeodeticGNSSantenna
oraCHCGNSSChokeRingantenna.

OtherGNSSantennasmayhoweverbeusedensuringthattheantenna
receivetheproperGNSSfrequenciesandoperatesateither3.3Vor7.1V
withasignalgreaterthan40dBattheantennaport.
