Cheap Chinese Antenna.
Not sure how/where you are going to mount it, but there's some issues...
-It's a 1/4 wave VHF antenna, but that mount is not going to provide a ground plane on its own. That's going to reduce performance.
-If that's being mounted outside, or on a vehicle, the underside of the NMO mount is not waterproof, and that's going to result in damaged cable if it gets damp.
-Price is a solid "meh". You could do better with name brand gear for similar price.
