    the cylinders are to shield the antenna from sources coming from the side. that is an array of radio telescopes.

    Thank's nsaspook, I got it.
    I read bertus' link.......looked at my pic again........and was still puzzled.
    Then I saw your pic and realized that there was a cap on the end. I thought the structure was open, I didn't see reflector.
    Thank you gentlemen.
