  1. This is an excellent review of the OB7-3.

    Can you tell me – does this antenna require a “boom truss?” Your photo looks like it has a boom truss, but you also describe a pulley that is used to raise and lower the antenna. Does the picture of the pulley make it look like it has a truss when it does not have a truss?

  2. Your antenna article was very useful as I am considering this model of antenna for myself. Thank you for doing such a complete job with photos and plots and lots of data!
