The Scala TY series are rugged broadband yagi antennas fabricated of aluminum rod and extruded pipe, anodized for maximum reliability and corrosion resistance. The hardware and fastenings are stainless steel. The internal balun, coax feed and connector are sealed in a foam potting system to prevent moisture penetration and assure long service life in severe environmental conditions. The heavy aluminum mounting casting allows installation for V or H polarization. The TY-900 is specifically designed for professional fixed- station applications in the 890-960 MHz band.
