    Why does coaxial cable make a good antenna feed line?
    It is weatherproof, and its impedance is higher than that of most amateur antennas
    It is weatherproof, and its impedance matches most amateur antennas
    It can be used near metal objects, and its impedance is higher than that of most amateur antennas
    You can make it at home, and its impedance matches most amateur antennas

    B-006-03-02
    What is the best antenna feed line to use, if it must be put near grounded metal objects?
    Ladder-line
    Twisted pair
    Coaxial cable
    Twin lead

    B-006-03-03
    What are some reasons not to use parallel-conductor feed line?
    You must use an impedance-matching device with your transceiver, and it does not work very well with a high SWR
    It does not work well when tied down to metal objects, and it cannot operate under high power
    It does not work well when tied down to metal objects, and you must use an impedance- matching device with your transceiver
    It is difficult to make at home, and it does not work very well with a high SWR

    B-006-03-04
    What common connector usually joins RG-213 coaxial cable to an HF transceiver?
    A PL-259 connector
    An F-type cable connector
    A banana plug connector
    A binding post connector

    B-006-03-05

    RG-213
    RG-58

    B-006-03-08
    Why should you regularly clean, tighten and re-solder all antenna connectors?
    To help keep their resistance at a minimum
    To keep them looking nice
    To keep them from getting stuck in place
