386 T0B06 What is the most important safety precautionT0B06 What is the most important safety precaution to observe when putting up an antenna tower? Install steps on the tower for safe climbing Insulate the base of the tower to avoid lightning strikes Ground the base of the tower to prevent lightning strikes Look for and stay clear of any overhead electrical wires
387 T0B07 How should the guy wires for an antenna tower be installed?So each guy wire anchor point has an even number of wires So that no guy wire is more than 25 feet long Each guy wire must be pulled as tight as possible In accordance with the tower manufacturer's instructions
388 T0B08. What is a safe distance from a power lineT0B08 What is a safe distance from a power line to allow when installing an antenna? Half the width of your property unless the wires are at least 23 feet high 12.5 feet in most metropolitan areas 36 meters plus 1/2 wavelength at the operating frequency So that if the antenna falls unexpectedly, no part of it can come closer than 10 feet to the power wires
389 T0B09. What is the most important safety rule toT0B09 What is the most important safety rule to remember when using a crank-up tower? This type of tower must never be painted Crank up towers must be raised and lowered frequently to keep them properly lubricated Winch cables must be specially rated for use on this type of tower A crank-up tower should never be climbed unless it is in the fully lowered position
390 T0B10. Why is stainless steel hardware used onT0B10 Why is stainless steel hardware used on many antennas instead of other metals? Stainless steel is a better electrical conductor Stainless steel weighs less than other metals Stainless steel parts are much less likely to corrode Stainless steel costs less than other metals
391 T0B11 What is considered to be an adequate ground for a tower?A single 4 foot ground rod, driven into the earth no more than 12 inches from the base A screen of 120 radial wires Separate 8 foot long ground rods for each tower leg, bonded to the tower and each other A connection between the tower base and a cold water pipe
392 T0C01 What type of radiation are VHF and UHF radio signals?Gamma radiation Ionizing radiation Alpha radiation Non-ionizing radiation
393 T0C02 When can radio waves cause injury to the human body?Only when the frequency is below 30 MHz Only if the combination of signal strength and frequency cause excessive power to be absorbed Only when the frequency is greater than 30 MHz Only when transmitter power exceeds 50 watts
394 T0C03. What is the maximum power level that anT0C03 What is the maximum power level that an amateur radio station may use at frequencies above 30 MHz before an RF exposure evaluation is required? 1500 watts PEP transmitter output 1 watt forward power 50 watts PEP at the antenna 50 watts PEP reflected power
395 T0C04. What factors affect the RF exposure ofT0C04 What factors affect the RF exposure of people near an amateur transmitter? Frequency and power level of the RF field Distance from the antenna to a person Radiation pattern of the antenna All of these answers are correct
396 T0C05. Why must the frequency of an RF sourceT0C05 Why must the frequency of an RF source be considered when evaluating RF radiation exposure? Lower frequency RF fields have more energy than higher frequency fields Lower frequency RF fields do not penetrate the human body Higher frequency RF fields are transient in nature and do not affect the human body The human body absorbs more RF energy at some frequencies than others
397 T0C06. How can you determine that your stationT0C06 How can you determine that your station complies with FCC RF exposure regulations? By calculation based on FCC OET Bulletin 65 By calculation based on computer modeling By measurement of field strength using calibrated equipment All of these choices are correct
