3.0 INSTALLATION
3.1 General Information
This section contains information necessary for preparing the AM-SAT-50 for use.
Included are cable interconnections, wiring diagrams, and mounting dimensions for the Bias
Tee and Amplifier.
3.2 Preparation for Use
After unpacking the system and inspecting for physical damage, select an appropriate
location for the Bias Tee and Amplifier. The Bias Tee is usually installed with the radio and
power amplifier, in a location protected from the weather. The Amplifier is located close to the
antenna. Although the Amplifier is weather-proof, placing it in a location where it is protected
from direct salt spray, rain, and sunlight will tend to increase its service life.
3.3 Cable Interconnections
Attach the cables to the system as shown in Figure 3-1. Cable W1 is supplied
with the system and is detailed in Paragraph 3.4. Cables W2 and W4 may be RG-58,
RG-223, etc. Cable W3 should be RG-214 or better. The loss through cable W4 should
be kept below 0.75 dB for best performance. For example, 5 to 20 feet of RG-214 or 5
feet of RG-223 is acceptable. Table 3-1 provides some guidelines for cable length and
receive preamplifier gain settings.
Low-loss high performance Heliax cable may be used to greatly extend the remote
distance of the amplifier.
