    antenna Description

    The transmitter antenna must be used 50 ohms, frequency of about 100M
    antenna,
    cannot use instead of wire, rod antenna, 2.4G antenna, radio antenna and
    so on.


    GP antenna 65-375MHZ



    The appearance of the antenna is as shown.
    It is a more efficient FM transceiver antenna.
    It can also be placed outdoors. It can also be hung in the
    air.

    Each of the vibrators can be pulled according to
    the transmission frequency. It is more flexible than the GP
    antenna of the currently available fixed-length vibrator,
    making it more effective to resonate with the transceiving
    frequency. Achieve higher transceiving efficiency.

    The length of the four vibrators is 20 cm to 1.1
    m. It is suitable for wider frequency adjustment. The
    working frequency can be adjusted from 65 MHz to 375 MHz.

    For different transmission and reception
    frequencies, the length of each vibrator is (300/frequency)
    / 4 (meters), and the middle one is pulled up. The three
    surrounding ones are pulled downward by 45 degrees.

    For example, the transmission and reception
    frequency is 107.3MHZ. Then each vibrator has to pull:
    (300/107.3) / 4 = 0.699 meters,

    When you feel that the transmission distance of
    your FM transmitter or the sensitivity of the FM receiver is
    not satisfactory, connecting this antenna can have an
    immediate effect.
