    Mosely CL-33 Beam Antenna refurbishment by Rob W2RWS




    Paul, 

    Good evening.  Attached is a photo of the new beam antenna balanced on the ladder.  All it took was a ladder, a step stool, a can of bug spray and a 9/16” wench!  This thing is huge, but only 40 pounds!   

    Testing now;  So far, so good.  Made a contact with a guy in Vermont and the antenna is (W) facing Europe. 

    Below is a link to an antenna primer listing the CL-33.  It has illustrations of the strength  patterns of a Typical dipole at various distances(wavelengths) off the ground.  The ladder is about 8’, about 1/8 wavelength.  So it’s radiating mostly upwards.  The ladder may still interfere some; it’s insulated from the center beam with a piece of wood.

    (Gotta get the tower up some time soon.)

    Need to conquer the ‘rotate the ladder’ problem.  The XYL has declined that job....

    :-(

    Best!
