Step 4
Fold the braid back over the clamp. Comb the
braid to evenly distribute it over the clamp and trim
to the proper length as shown.
Step 5
Verify there is no braid or dielectric foil that may
short against the center conductor. Tin the center
conductor and then solder on the male contact as
shown.
Step 6
Insert the cable assembly into the connector body.
Verify the gasket “V” grooves fit into the clamp
edges. Hold the body with the 11/16” wrench and
tighten the nut using the 5/8” wrench. Using the
multi meter, measure continuity of the center
conductors on each end of the cable. It should be
close to 0
Ω . Measure the continuity between the
center conductor and connector body. It should
be an open circuit.

2.5 Model 8227 GPS Inline Amplifier
An inline amplifier is required whenever GPS antenna cable lengths cause greater than
12 dB attenuation. Using Spectracom CAL7xxx or LMR-400 coax, an amplifier is
needed whenever antenna cable lengths exceed 200 feet.
The Model 8227 GPS Inline Amplifier, shown in Figure 2-5, extends the maximum cable
length to 600 feet. The Model 8227 provides 20 dB of gain and is powered by the GPS
receiver.
Figure 2-5 Model 8227 Inline Amplifier
Each Model 8227 includes two clamp type male N connectors. These connectors can
be used to splice the Model 8227 into the antenna coax. The connectors are
compatible with LMR-400 type coax such as Spectracom CAL7xxx or LMR-400. Refer
to Figure 2-4 for connector assembly instructions.
