(A pair Antenna Paddles)
Directional antenna
Transmitting and receiving antenna
Frequency range: 470-950 MHz
Can be mounted on a microphone stand
This directional antenna offers enhanced reception of the desired coverage area and greater rejection of RF signals outside the coverage area when compared to an omnidirectional half wave antenna. It is for U4S, U4D, ULXP, UR4S and UR4D receivers or UA844 or UA845 antenna distribution systems.
Active Directional Antenna UA874
1.Products Features
Active directional antenna uses a log periodic array to offer enhanced reception when directed toward the desired coverage area.An integrated amplifier
and four gain settings compensate for varying degrees of coaxial cable signal
loss.Low-noise signal amplifier compensate for insertion loss in coaxial cable.
2.Products Installation
Connect the antenna to the receiver or distribution system using the cables
given(or any 50 ohm ,low-loss coaxial cable).
The antenna only operates with receivers or distribution systems that provide
10-15V DC bias.
Lower the gain setting for short cable runs,or increase gain for longer runs.
Note that the quality of the cable,not just the length,contributes to signal loss.
Direct the antenna toward the intended coverage area.
3.Products use
1.Gain switch
Adjust the four-position gain switch to compensate for the calculated cable
loss,based on the length and type of cable.
2.Gain mode LED
Indicates the current gain switch setting.
3.RF Overload LED
Indicates a strong RF signal that is overloading the antenna amplifier,which
results in distortion or poor performance.Increase the distance between the
antenna and transmitter,or lower the antenna gain setting.
Note:RF Overload LED does not operate for passive gain settings -6dB or 0
dB).
4.BNC connector
Connect to a receiver or antenna combiner with RF inputs that supply 10-15V
DC bias
