    Practice


    B-003-20-01
    Why should you ground all antenna and rotator cables when your amateur station is not in use?
    To lock the antenna system in one position
    To protect the station and building from lightning damage
    To avoid radio frequency interference
    To make sure everything will stay in place

    B-003-20-02
    How can an antenna system be protected from lightning damage?
    Install a balun at the antenna feed point
    Install an RF choke in the antenna feed line
    Install a fuse in the antenna feed line
    Ground all antennas when they are not in use

    B-003-20-03
    How can amateur station equipment best be protected from lightning damage?
    Disconnect all equipment from the power lines and antenna cables
    Use heavy insulation on the wiring
    Never turn off the equipment
    Disconnect the ground system from all radios

    B-003-20-04
    What equipment should be worn for working on an antenna tower?
    A reflective vest of approved color
    Approved equipment in accordance with provincial safety standards concerning climbing
    A flashing red, yellow or white light
    A grounding chain

    B-003-20-05
    Why should you wear a safety belt if you are working on an antenna tower?
    To safely bring any tools you might use up and down the tower
    To keep the tower from becoming unbalanced while you are working
    To prevent you from accidentally falling
    To safely hold your tools so they don't fall and injure someone on the ground

    B-003-20-06
    For safety, how high should you place a horizontal wire antenna?
    Above high-voltage electrical lines
    Just high enough so you can easily reach it for adjustments or repairs
    High enough so that no one can touch any part of it from the ground
    As close to the ground as possible

    B-003-20-07
    Why should you wear a hard hat if you are on the ground helping someone work on an antenna tower?
    So you won't be hurt if the tower should accidentally fall
    To keep RF energy away from your head during antenna testing
    So someone passing by will know that work is being done on the tower and will stay away
    To protect your head from something dropped from the tower

    B-003-20-08
    Why should your outside antennas be high enough so that no one can touch them while you are transmitting?
    Touching the antenna might reflect the signal back to the transmitter and cause damage
    Touching the antenna might radiate harmonics
    Touching the antenna might cause RF burns
    Touching the antenna might cause television interference

    B-003-20-09
    Why should you make sure that no one can touch an open-wire feed line while you are transmitting with it?
    Because contact might break the feed line
    Because high-voltage radio energy might burn the person
    Because contact might cause spurious emissions
    Because contact might cause a short circuit and damage the transmitter

    B-003-20-10
    What safety precautions should you take before beginning repairs on an antenna?
    Be sure to turn off the transmitter and disconnect the feed line
    Be sure you and the antenna structure are grounded
    Inform your neighbors so they are aware of your intentions
    Turn off the main power switch in your house

    B-003-20-11
    What precaution should you take when installing a ground-mounted antenna?
    It should be painted so people or animals do not accidentally run into it
    It should not be installed in a wet area
    It should be installed so no one can come in contact with it
    It should not be installed higher than you can reach
