1.5 AM-SAT-50 SYSTEM
The AM-SAT-50 is pictured in Figure 1-1. A functional block diagram is
shown in Figure 1-2.
1.5.1 Bias Tee
The Bias Tee consists of two printed circuit assemblies in a divided aluminum housing.
The DC input connection and RF connection to the radio are located on one end of the Bias
Tee. The Power On/Off switch and RF connection to the Amplifier are located on the opposite
end. When assembled, the enclosure is splash-proof, and may be mounted in any convenient
position.
1.5.2 Amplifier
The Amplifier consists of several printed circuit assemblies, a filtering and switching
network, and associated connectors and switches housed in a watertight aluminum housing.
With normal care and maintenance, the assembly is highly resistant to corrosion from the
elements. The interconnections to the Amplifier are made via two female type N connectors.
Through holes are provided on the base plate for mounting purposes. A DC power connector is
provided on the amplifier for connection to a DC power source when remote operation is not
required, such as vehicle installations.
1.5.3 Power Cable
A five-conductor cable connects the AM-SAT-50 with a DC power source. A wiring
diagram for the cable is shown in Section 3 of this manual. The power cable may be attached to
either the Bias-Tee or directly to the amplifier.
