Hi John,
You don’t say WHICH remote antennas you are using. The connections on the end of Rosetta are ‘SMA Female’ so you need ‘SMA Male’ on the matching cable ends. If you are using the PAW External antennas, the connectors on them are ‘BNC Female’, so you need ‘BNC Male’ on the matching cable ends.
Beware you may also come across RP-SMA (Reverse Polarity SMA) in which the ‘Male’ connector has the socket and the ‘Female’ connector has the pin. They WILL NOT fit with ‘normal’ SMA - just be careful.
Regards
Peter
