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 seaparated 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 seaparation would have to be meters. The capacitive reactance that does exist can be accomodated 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 quetions for the moment. Thanks for your help. |
