    Good question Homer. What was your 1st question?

    To me it sounds like a guy selling maybe $10 of plastic and wire for $57.

    If the intent is an antenna consisting of two perpendicular dipoles, a better, less confusing name is needed. AND, each leg should be a quarter wave in length. As is, there are two full wave dipoles and a major impedance problem.

    If it were two half wave dipoles, and each were a different band (say 10 and 11 meters), it would then perform as a cobweb.

    Am guessing the designer’s intent of having perpendicular dipoles is a four lobe, omnidirectional pattern if hung horizontally as opposed to the more directional pattern of a single dipole. Good in theory but . . .

    Tokin,
    Didn’t see that. Guess he does know what he’s doing. :D

    Marconi,
    Eddie, is this something you can model?

    The first question is "What is this?"

    It is a big plus (+) sign in the sky...

    Maybe it is sold as an 11m antenna but it's really a non resonant 20m multiband daddy long legs non articulating limbs RF spider... o_O

    I am tempted to make one. Got the wire. Got the balun. Need the time.
    Wife's been working from home since mid-March and looks like doing so until 1st of July... maybe.
    Crimping my antenna style.

    You may be onto something. The Daddy Long Legs Non-Articulating Spider antenna. I’d buy one of those before I’d buy a Quad Element 11 Meter Dipole just on name alone. Bet you could sell some. (y)

    If the elements were half as long, it would be a turnstile antenna of some sort.

    But half-wave long wires should give it a horrendously high feedpoint impedance.

    I'm baffled.
