Ohm's Law Equation for RG-6 - CORRECT ANSWER-34.1Ω per 1000ft; .0341Ω per foot
Ohm's Law Equation for RG-11 - CORRECT ANSWER-16.1Ω per 1000ft; .0161Ω per foot
What is the clearance required for our drops to be from power at the pole? - CORRECT
ANSWER-40"
What is the clearance required for our drops to be from phone at the pole? - CORRECT
ANSWER-12"
What is the clearance required for our drops to be from power at the house? - CORRECT
ANSWER-12"
What is the clearance required for our drops to be from phone at the house? - CORRECT
ANSWER-4"
How far above a residential walkway does our drop have to be? - CORRECT ANSWER-9'6"
How far above a residential driveway does our drop have to be? - CORRECT ANSWER-11'6"
How far above a public road does our drop have to be? - CORRECT ANSWER-15'6"
How far above a public highway or interstate does our drop have to be? - CORRECT ANSWER-18'
, What is the sag ratio for aerial drops? - CORRECT ANSWER-6" per 50ft of coax
How far does a Q-clamp have to be from the center of the pole? - CORRECT ANSWER-24"
How far does a Q-clamp have to be from the tap? - CORRECT ANSWER-6"
At what point does the FVD audibly tone? - CORRECT ANSWER-50 volts
What is the downstream/Rx bandwidth range? - CORRECT ANSWER-50-860 mHz
What is the upstream/Tx bandwidth range? - CORRECT ANSWER-5-42 mHz
What is MER? - CORRECT ANSWER-Modulation Error Ratio, It is a measure of how the QAM
signal is received. Similar to a target for a bow and arrow, a perfect hit would be dead center
with no varying points askew. This is literally represented in a constellation view.
What is BER? - CORRECT ANSWER-Bit Error Rate, It is the number of bit errors per stream of
bits. This is found by dividing the number of errors by the number of bits sent. This is also
known as the quality of signal being transmitted. In the bow and arrow analogy, BER is
represented by the arrow.
What is the MER range amount to pass on the meter? - CORRECT ANSWER-33-51 dBmV
What is the ideal measurement for BER? - CORRECT ANSWER-1.0E-9
What is ingress? - CORRECT ANSWER-Unwanted signal leaking into the cable due to service
issues or faulty equipment
