Connectors and transmission cable. If you plan to have the antenna outside then weatherproofing materials and possibly a mast and/or mounting brackets. If you mount above roofline then lightening arrestors and grounding wire. If your just talking about inside your house then the AP, the omni or directiona antenna (depends on what your trying to do), the transmission cable (coax and depends on length as to what kind) and the connectors, both for the antenna connector and your AP post.
