All element sides, also the passive ones, have 8 contacts which connect to the copper band inside the element tubes. The installation of these contacts assures a constant spring pressure and reliable electrical contacts. Due to the constant movement of the copper tape the contacts are permanently cleaned. With passive elements these contacts join the two halves of the element. With active radiators the HF energy is coupled to the element by these contacts.
