    Re: Lights etc. - aluminum foil in mast

    Hi Jared:
    
    My guess is that is a product is very simple and low cost it's difficult
    to sell it commercially.  Also note it's not easy to get three wires to
    be at right angles to each other.  And they only will works on the one
    frequency they have been cut for.
    
    The onion type is called a Lunberg (spelling?) Lens, expensive to make.
    
    The corner reflector is typically made with 8 "corners"  by 3
    intersecting planes.  This way there always will be signal returned to
    the source radar independent of the illumination direction.  These are
    fairly easy to make, but need to be sized for the lowest frequency radar.
    
    Have Fun,

    spheres and layers like an onion, the other the plain "disposable" David foil 
    on cardboard model, using the corner reflector theory.

    proposed as a low-windage alternative?
