Choosing this model
GL450XTS1 selection guide
GL450XTS1 is the ceiling-mount choice with nut fixing. Compare it with GL450BKB only after deciding whether the installation needs a ceiling position or a wall-mounted antenna; their mounting methods are different.
For ceiling integration, check the circular body dimensions and clearance around the fixing point. GL450BKB has a different body shape and higher listed gain, but those differences do not establish that it will suit the same mounting location or coverage requirement.
