The patent-pending drop form of plastic antenna generates a smaller beam
angle (2º) than conventional antennas, eliminating the need for an
antenna-aiming kit to amplify the reflected signal. Users can choose a
3-in. diameter (DN 80) antenna made of Polypropylene (PP) or Teflon
(PTFE), or a 6-in. (DN150) PP. Conventional stainless steel horn
antennas up to 6 inches (DN 150) with a built-in horn purging feature
are also available.Krohnewww.KROHNE.com/northamerica800.FLOWING
