Antenna Installation Tools And Materials - Symmetricom TimeProvider 100 User Manual

Use #6 AWG (13.3 mm) copper ground wire or larger, depending on the distance
to the earth ground electrode. Refer to your local electrical codes for specific
details. In most cases, 1/0 AWG (55.0 mm) ground wire will maintain 1/10 the
resistance of the coaxial shied.
Note: Larger ground conductors provide better transient elimination;
that is, the larger the ground conductor, the less likely the chance of
transients.
Connect transient eliminators, if part of the grounding scheme, to earth ground

through a conductor.
Symmetricom makes no recommendation as to whether to install transient
eliminators. Symmetricom can provide suitable transient eliminators as an option.
Note:
inside equipment rack ground. Doing so can defeat the protection
afforded by the transient eliminator.
Never connect antenna systems to the same earth ground connector as heating

and cooling systems, elevator or pump motors, or other motors or machinery
which can induce noise in the antenna system.
