- UA845 Micphone Amplifier
UA845 is a UHF active wireless pointing antenna with a dual-polarized log-periodic array. In contrast to the 1/2 wavelength omnidirectional antenna, UA845's heart-shaped pickup mode can more effectively receive signals in a predetermined coverage area and more effectively resist radio frequency signals outside the coverage area.
To compensate for coaxial cable signal loss, UA845's on-board amplifier provides a user-selectable 3 or 10dB gain. The gain setting is indicated by two LEDs. The antenna amplifier is powered by a remote 12V DC power supply and is supplied by the UA845 antenna distribution system via a coaxial cable. The UA845 can be mounted on a microphone stand, suspended from the ceiling, and mounted on a wall using a rotary adapter bracket. UA845 can withstand the adverse weather, suitable for outdoor use. Two UA845 antennas are used for optimum diversity performance. UA845 signal distribution system, 5 Road, broadband UHF (470-960MHz), external 4 groups of 12V / 1A Dc current (DC power supply).
