    I have an aero. search and rescue beacon transceiver from a Govt.
    surplus store.
    When I connect the homemade(bike spoke) ant. to the casing(at the same

    time it is connected to the proper ant.input site) it changes to
    receiving a different air to ground conversation,than if I don't
    connect it to the casing.I presume it must be changing the frequency of

    transmission received.
    Why/how does this occur?.
    Thanks.

    Hi,
    You may be experiencing detuning of the front end circuit due to antenna
    mismatch.
    The antenna will appear inductive or capacitive if the circuit is not loaded
    properly. Use an antenna of the proper length for that unit.
    I would expect a unit of that type to be tolerant of this however. Perhaps
    you have some internal problems that can not be seen from where I sit.
    Regards,
    Tom

    Thanks for the info.,Tom.
    When I 'earth' the ant. to the body it also cancels the interference
    with our tv channel reception.I works ok for my purposes,just intrigued
    why earthing the ant. to the body changes conversation recieved.
    I'm thinking of using a 50ft wire to extend ant. to see what I
    receive.
