The Scala TY-900 is a rugged broadband yagi antenna specifically designed for professional fixed-station applications in the 890-960 MHz band. The TY-900 is fabricated of 6061/T6 aluminum rod and seamless drawn pipe, anodized for maximum reliability and corrosion resistance. The internal balun, coax feed and connector are sealed in a foam potting system to prevent moisture penetration and assure long service life. Input power rating is 100 watts, gain is 10 dB and impedance is 50 ohms.Specifications:Frequency range: 890960 MHzGain: 10 dBd (12.15 dBi)Impedance: 50 ohmsVSWR: <1.5:1 maximum (1.35:1 typical)Polarization: Horizontal or verticalFront-to-back ratio: >20 dBMaximum input power: 100 watts (at 50C)H-plane beamwidth: 48 degrees (half-power)E-plane beamwidth: 40 degrees (half-power)Connector: N femaleWeight: 3 lb (1.4 kg)Dimensions: 23 x 6.8 inches (584 x 173 mm)Wind load at 93 mph (150 kph), Front / Side: 3 lbf / 4 lbf (11 N / 17 N)Wind survival rating*: 150 mph (241 kph)Shipping dimensions: 28 x 10 x 4.5 inches (maximum) (711 x 254 x 114 mm)*Mechanical design is based on environmental conditions as stipulated in TIA-222-G-2 (December 2009) and/or ETS 300 019-1-4 which include the static mechanical load imposed on an antenna by wind at maximum velocity.
