Baofeng Tech: Antenna Connections

A commenter wanted "to know if that antenna has any kind of O-ring or seal between the antenna and NMO adapter." Here are some close-ups of all the connectors for both the Nagoya TB-320A tri-band antenna and the Nagoya RB-35 5/8 NMO Mount. I don't see any o-rings/seals - just the insulators, but the fit was very good on everything and all the connections locked up nice and tight.
