4 Zone Antenna Combiner . 4 ZONE™ Antenna Combiner. The 4 ZONE™ antenna combiner takes the complexity out of multizone wireless microphone projects. This wideband combiner (470-960 MHz) brings together up to four separate pairs of diversity antenna connections for multipurpose rooms, indoor-outdoor configurations, or main stages with secondary breakout rooms.
For fine tuning RF levels in each coverage area, 4 ZONE provides individual channel RF signal attenuation control down to -31dB in 1 dB steps. And for active antennas or in-line amplifiers, it features selectable 12V DC power to accommodate long cable runs.
With selectable on/off inputs, 4 ZONE also allows for quick control of coverage zones for roaming microphone transmitters, so you can choose which zones are active. When used in conjunction with up to four Diversity Fin Antennas and one or more DISTRO4 antenna distributors, 4 ZONE completes a turnkey package for any multizone wireless microphone project.
