    I have been researching SSB installation issues and am left with a couple of
    questions.

    First, antenna installation. I intent to use a long wire through a tuner to
    operate on HF. I intend to use an insulated shroud (I have a cat with no
    backstay) with a short feed from the tuner. I have always believed that the
    feed wire should be separated from the rigging before it reaches the
    connection point to reduce capacitive reactance. I have accomplished this
    in the past with 2" spacers holding the wire off of the shroud until it
    reached the connection point. Recently, I read a credible opinion that
    separation of an inch or two is irrelevant at high frequencies because to
    eliminate all capacitive reactance the separation would have to be meters.
    The capacitive reactance that does exist can be accommodated with the tuner.
    If this is true I would prefer to directly attach a long insulated wire to
    the shroud - perhaps tape it over a 25 foot length. It would be out of the
    way, safe from rf burn risk and would not require the installation of
    rigging isolators which introduce mechanical weakness and expense.

    My second set of questions relate to ground plane/counterpoise installation
    but I'll hold of on those questions for the moment.

    Thanks for your help.
