ST-9940 antenna signal distributor (4-way)

The ST-9940 is a UHF active wireless directional antenna with a dual polarized log periodic array. Compared to a 1/2 wavelength omnidirectional antenna, the cardioid polar pattern can more effectively receive signals in a predetermined coverage area and more effectively cover RF signals outside the area. To compensate for signal loss from coaxial cables, onboard amplifiers provide users with optional 3 or 10 dB gain. The gain setting is displayed by two LED lights. The antenna amplifier is powered by a remote 12V DC power supply and is provided by the antenna distribution system through coaxial cables. It can be mounted on a microphone stand, suspended from the ceiling, or mounted on a wall using a rotary adapter bracket. It can withstand the impact of bad weather and is suitable for outdoor use. Using two antennas provides optimal diversity performance.
