    The reason the construction diagrams show in insulator between two sections - with just two holes to let the wires through - is so the braid on one section can not come into contact with the braid on the next.

    Even if you took great care in calculations and building the antenna, it is difficult to get it right without proper test equipment that works at 1090Mhz - and the more elements you add, the worse the problems get.

    Try just 4 elements.

    I bought a commercial antenna to be sure of a good result.

    Ok I will try 4 elements, now my question is, do i have to put the connector in the 4th element or add another cable and then the connector?

    sorry, I don't understand why you need a connector apart from the one on the end of the downlead.
