Cable Route
When choosing a cable route for coaxial cable, consid
the following:
Avoid ru
too power cables and high power RF cables.
Ensure
edges or places where the cable could become
pinched or damaged in any way.
Determine the manufacturers specifications for
the coaxial cable in use. This should include:
impedance
,
diameter, attenuation in dB/100ft
and dB/100m at 1.575GHz, velocit
propagation and the minimum bend radius of the
cable.
Ensure the cable does not exceed the
recommended minimum bend radius suggested
by the manufacturer.
Ensure there is sufficient space at the c
entry point to the bulkhead as to not damage the
connector during installation.
Measure the length of the cable route and ref
to Table 8 for acceptable cable lengths in
relation to attenuation loss at the frequencies in
