Self-Support Tower What type of tower is supported by wires anchored into the ground and requires the greatest amount of land use? Guyed Tower When climbing a guyed tower what must be inspected before the climb? Point of Daylight What type of tower is built in various ways to ensure it blends with the surroundings? Stealth Tower What type of tower is a single tube tower and the antennas are mounted on the exterior of the tower? Monopole What is the ladder like structure that runs up the tower and supports transmissions lines? Waveguide What is used on monopole towers to guide the cable in and out of the tower? Port Hole What component improves the ability to hear received signals? Tower Mounted Amplifier (TMA) What type of antenna mount is primarily used on monopoles and has limited anchor points? T-Boom What compnent is mounted on the tower to provide lightning protection? SQUID 3 RF work place hazards? Non-Ionizing Radiation Radio Frequency Energy The energy beaming from a transmitting or "hot" antenna What are the hazards of being exposed to RF? Heating of your body tissues Damage to rigging equipment from arcing A painful RF burn What does MPE mean? Maximum Permissible Exposure Who is responsible to keep you safe from RF hazards in the work place? The Employer What is the meaning of the Blue "NOTICE" RF signs? You are entering an area where you may encounter RF levels exceeding safe exposure limits- proceed with care What is the meaning of the yellow "CAUTION" RF signs? You are entering an area where you will be exposed to RF levels up to MPE limits- proceed only if trained What is the meaning of the red "WARNING" RF signs? You are entering an area where RF levels exceed MPE limits- proceed only if protective measure are taken What capstan hoist feature helps control the on/off function? Foot switch/pedal When should you inspect the capstan hoist? Before each use Why do you need to ensure the capstan hoist is the only item connected to the electric power source? Other tools reduce the flow of electricity to the capstan Reduced flow will reduce the pulling power Can burn out the capstan motor The anchorage strength must have a design factor of what? 2 times the load What must you do to the vehicle when using a receiver hitch?

Minimum Breaking Strength What does FS stand for? Factor of Safety What does WLL stand for? Working Load Limit When wrapping the rope on the drum where will the loadside be positioned? Inside of the drum When wrapping the rope on the drum where will the pull side be positioned? Outside of the drum What can happen if the rope is to small or large for the sheave? The WLL of the rope will be reduced What must you do of the rope overlaps? Stop the operation Secure the pull line Controlled method to remove the load weight When lowering the load how many wraps/turns of the rope are required? same number required to lift the load PPE required when using capstan hoist? Hard Hat Leather Gloves Safety Glasses Safety Toe Boots What will you use to gain more control of the load while keeping it away from the structure? Trolley tag system What type of system are you using if you run the load line through a heal block? Straight Tag System The antenna sector usually orients north is? Alpha Sector The degrees an antenna is facing in reference to true north is? Azimuth The main transmission line in a cell circuit is called what? Hardline
