Instruction Sheet

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.

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
to four receivers thus eliminating excess power
supply clutter.

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.
