DomeAnt-Alpha&trade; Omnidirectional Ceiling Antenna for Boosters, Amplifiers, Repeaters The DomeAnt-Alpha&trade; is a high-efficiency dome antenna for ceiling installations with a discreet and elegant outline. The DomeAnt-Alpha&trade; features ultra wide operational bandwidth and can be used with boosters/amplifiers/repeaters as the internal antenna. The DomeAnt-Alpha&trade; requires flush mounting via a small hole in the ceiling. The DomeAnt-Alpha&trade; operating frequency range is 700-3800 MHz with a peak gain of (varies) dBi*, a horizontal aperture of 360&deg; and a vertical aperture of 100&deg;.
