e. Loops shall be formed in the aerial cable at points of connection
and at poles to prevent damage from thermal stress and wind loading.
The communication cable shall be protected from chafing and physical
damage with the use of spiral cut tubing and PVC tape, or plastic
sleeves. The ground clearance of installed cabling shall be as shown.

ENCLOSURE PENETRATIONS
Enclosure penetrations shall be from the bottom and shall be sealed with
rubber silicone sealant to preclude the entry of water.
3.3
IMPULSE SUPPRESSION SURGE ARRESTER GROUNDING
Impulse suppression surge arresters shall be grounded. Ground resistance
shall be not more than 10 ohms. Connections to earth shall be made in the
same manner as for secondary neutral ground rod. The aerial portions of
surge arrester and secondary neutral ground conductors shall be separate
from and independent of each other but both grounds shall be bonded
together below grade at the ground rods, or to the ground counterpoise, as
applicable and the ground rods shall be spaced a minimum of 6.1 meters 20
feet apart.

TESTING
3.4.1
General
Demonstrate compliance of the two-way Radio Data transmission System with
the contract documents. Furnish personnel, equipment, instrumentation, and
supplies necessary to perform site testing. Ensure that test personnel are
regularly employed in the testing and calibration of radio data
transmission systems. Testing shall include the field tests and the
performance verification tests. Field tests shall be conducted by the
contractor to determine the system is completely operational. Performance
verification test shall be a demonstration to the Government to ensure
proper operation of all the components and proper execution of the sequence
of operation.
3.4.2
Government Furnished RFCE Test
The Contractor shall test the Government furnished RFCE and certify that
the equipment is in calibration and functioning correctly.
3.4.3
Test Plan
Submit and obtain approval of the field test plan and performance
verification test plan for each phase of testing before beginning that
phase of testing. Give to the Contracting Officer written notification of
planned testing at least 30 days prior to test. Notification shall be
accompanied by the proposed test procedures. In no case will the
Contractor be allowed to start testing without written Government approval
of field test plan and performance verification test plan.
3.4.4
Contractor's Field Test
The Contractor shall verify the complete operation of the two-way radio
data transmission system during the Contractor's Field Testing. The
Contractor's Field Test shall include an error rate test. The Contractor
shall perform the test by sending 100,000 commands and measuring the error
rate. The error rate shall be not greater than 5 out of 100,000. The
