> Product Overview

The 301121 antenna from Wilson is an internal ceiling mount dome antenna. To form part of a cellular amplifier system, it should be installed on the ceiling in the center of the area you want the cellular signal to be improved in. This antenna will rebroadcast cellular signal after it has been boosted by the amplifier unit. The antenna is dual band and is thus suitable for use with cell phone amplifiers which operate on 800 Mhz, 1900 Mhz and iDEN frequencies.
