Caps/plugs for unused antenna ports?

[Jenni McWright]

Just a quick question that I can't seem to find an answer to--- are caps/plugs required to cover any unused antenna ports on an outdoor 1532e AP? My installer says there should be but says there aren't any that fit in the box of equipment I gave him.

Unused connections are capped with a connector plug to ensure the watertight integrity of the access point. Liquid-tight adapters are provided for connector openings, which can be installed before or after deploying the access point.
