    Mosley is a highly respected name in amateur radio antennas.
    Outstanding quality and performance but relatively high priced.
    It seems they have an assortment of CB antennas as well. Beams, a mini-beam and a ground plane.



    Anyone using one of these?

    Gamma match and mini beam are names I would avoid :)

    The feed arrangement at the bottom of their "Devant Special" vertical antenna sure has a suspicious resemblance to Jay in the Mohave's Interceptor antenna.

    Except Jay's antenna probably has three or four times the metal in it. And his is a 5/8- wave, not a half-wave like the Moseley.

    But this is the only place I remember seeing a feedpoint setup even similar to Jay's setup.

    ???

    Honestly, I'm not sure if that matching system will work very well for a half wavelength antenna. Perhaps I should try and model it sometime...

    I agree with DB (???), the Mosley website says it is a 5/8 wave.

    I often wondered if this "Devant Special" could have been the genesis of Jay's I-10K.

    Is it legal to sell metal 11 meter antennas?

    Why wouldn't it be legal?

    Mini beam = mini signal!
    If you have room for a mini beam you have room for a real beam.

    It seems I recall regulations requiring cb antennas to be insulated from contact with power lines. I don't recall where I saw this, or if it is actually true.

    Pretty sure the workaround for this is to label and market it as a "commercial" antenna. This prevents it from being a "consumer" product.

    The theory is that a "CB" antenna is a consumer product, and comes under the jurisdiction of the Consumer Product Safety Commission.

    A commercial antenna does not. Pretty sure an "amateur" antenna doesn't, either.

    The regulation - which will require warning labels, safety installation instructions, and written information on hazards- will affect an estimated 150 manufacturers of citizen band (CB) base station antennas, television antennas, and certain antenna supporting structures.
    CPSC estimates that the cost of labels and installation instructions to the manufacturer will be between 10¢ and 35¢ per product item with a probable increase in the retail price of approximately $1 per unit. CPSC believes that the cost is justified in view of the severe nature of the hazard associated with these products.

    That's not a law that would pertain just to CB antennas. Any insulation that would be sufficient to protect from the main line voltages would make it too heavy to put up.
    7000 volts will find any flaw in the insulation and roast you.
    That notice is a precautionary statement to get the manufacturer off of the hook should you make accidental contact with the power lines. I just read another post that said it would have to withstand 14000 VAC for 10 minutes, not very likely to pass.
