General Description
The UAD4 Amplified Antenna Splitter makes it
possible to operate four UHF wireless diversity
microphone receivers on four separate frequen-
cies using only two antennas.
Frequency Range 301614100 .................................................................................600-780 MHz
3rd Order Intercept Output ...........................................................................greater than 18 dbm
Net Gain ............................................................................................................greater than 2 dB
Noise Figure ...........................................................................................................less than 3 dB
Output Isolation...............................................................................................greater than 20 dB
Connectors, Antenna..........................................................................Standard TNC receptacles
Power Requirements................................................................................. 100-240VAC 50/60Hz
Features
The UAD4 is equipped with TNC type connec-
tors. Low loss coaxial cables are also supplied
for splitter to receiver antenna jack connections.
The UAD4 has an internal power supply. Power
out jacks and cables are provided to supply up

AMPLIFIED UHF
ANTENNA SPLITTER
It also features a high degree of output isolation;
a necessity in multi-frequency systems to prevent
intermodulation.
The UAD4 Splitter is compatible with Telex
UHF diversity wireless receivers.
Rack panel mounting "ears" allow the UAD4 to
be mounted in a standard 19 inch equipment
rack. "Knock outs" in the ears allow front con-
nection of antenna cables.

- Page 2 System Configuration Figure 2 illustrates the typical system configura- tion using the UAD4. Figure 3 illustrates an arrangement where two splitters have been cascaded. By connecting one of the outputs of the first splitter to the antenna inputs of the second splitter, three additional re- ceivers may be driven by a single pair of anten- nas.

- Page 4 Antenna Requirements The UAD4 may be used with a variety of anten- nas. For best results, use a pair of ALP-450 di- rectional log periodic antennas. See Figure 4. The ALP-450 offers the best performance and broadest bandwidth available. T elex...
- Page 5 (not supplied). Rack Mounted Antenna Connectors Antenna cable connections may be made to the front of the rack mounted UAD4 by installing the adaptor cables supplied. Proceed as follows: Remove the plug “knock outs” from the front panel. See Figure 6.
- Page 6 12 volt power is available on the center pin of the antenna in jacks. This power is disabled when the UAD4 leaves the factory but may be turned on by the installer. To turn on the 12 volts, first take off the cover of the splitter by removing the screws.
