What is the primary purpose of a sweep test performed on coaxial cable after installation?
Answer: To verify signal loss and return loss meet specifications
A sweep test measures insertion loss and return loss across a frequency range to verify the installed cable and connectors meet manufacturer specifications.
When routing coaxial cable on a tower, what is the recommended practice for weatherproofing connectors?
Answer: Apply weatherproofing tape and sealant per manufacturer specifications
Weatherproofing connectors with proper tape and sealant prevents moisture intrusion that can degrade signal quality and cause connector corrosion.
What is the correct method for securing transmission line to a tower structure?
Answer: Use approved hangers at manufacturer-specified intervals with proper bend radius maintained
Manufacturer-approved hangers at specified intervals support the cable weight while maintaining proper bend radius, preventing signal degradation and physical damage.
Before hoisting antenna components to the top of a tower, what must be verified first?
Answer: The rigging plan has been reviewed and all attachment points are rated for the load
Verifying the rigging plan and load ratings of all attachment points prevents overloading that could cause equipment drops and serious injury or death.
What grounding requirement applies to antenna transmission lines at the point of entry to a building?
Answer: Each transmission line must be grounded to an approved ground system per NEC Article 820
NEC requires all antenna transmission lines to be grounded at the building entry point to protect equipment and personnel from lightning and static discharge.
What is the purpose of installing a hoisting grip on coaxial cable during tower installation?
Answer: To distribute pulling force evenly and prevent cable damage during lifting
A hoisting grip distributes the pulling force across a section of cable rather than concentrating it at one point, preventing crushing, kinking, or stretching.
