[Antennas] Re: Elevated Ground Plane Question

[Ron W7MRR]

 Hi All:

   I have a 160 meter, 1/4 wavelength wire vertical that is feed approximately 30 feet off the ground.  The radials are horizonal from the feed point and parallel to the ground.  I have the opportunity to raise the radials to a height that is almost as high as the top of the vertical radiator [approximately 160+ feet] and am wondering if this will enhance the antenna effectiveness or not.  I am concerned about wave cancelling.

   If anyone has a software program where this situation can be simulated, I would be very interested in the results.  I will try it out in any case, but am interested in what modeling or experience suggests.  Please note the radials would now start at the feed point some 30 feet off the ground with the other end being elevated to 160+ feet.

   Thanks for taking the time to read this and to share your thoughts with me.
