803C XXXXX803CXXXXX The Model 550 is an excellent choice for omni- directional HF communications, where both ground wave and skywave coverage are required. The 550s large diameter/height ratio provides excellent VSWR and pattern performance over a very wide frequency rangeup to 20:1 for the Model 550-6 that operates at full effi ciency down to 1.6 MHzmaking it one of the few broadband antennas optimized for the lower maritime bands. The true wideband capability of the 550 is achieved with full radiation efficiency. The antenna uses no tuners, special coupling units, terminations, resistors or lossy elements to achieve its high bandwidth, nor does it use any techniques or devices to couple RF energy to the ground, a technique sometimes used to increase bandwidth at the expense of effi ciency. Combine ground waves and skywaves for omnidirectional HF. The 550 is the simplest and safest antenna to erect in its class. The structure is fully stable during the rigging sequence, without the need for temporary guys. The antenna does not use a rigid ring to maintain the shape of the cone, which can be diffi cult to install safely. Once erected, the Model 550 has outstanding structural rigidity, without troublesome defl ections and mechanical oscillations that occur in antennas using rigid rings. As with all TCI antennas, the Model 550 employs high-quality, exhaustively tested components and materials. All radiators and catenaries are Alumoweld, a wire composed of a high-strength steel core and a highly conductive, corrosion-resistant coating of aluminum. All feedline and radiator insulators are made of high-strength glazed alumina, a material with an extremely low loss tangent, which is virtually impervious to the effects of UV and salt spray. Neither fi berglass nor other synthetic materials are used anywhere in the antenna. A working life of 25 years or more is standard with the Model 550. 550 Inverted Cone Antenna KEY FEATURES 1.632 MHz covers entire maritime mobile service Single tower 2.0:1 VSWR maximum anywhere in band Fully effi cient Rugged and safe to erect TCI INTERNATIONAL, INC. 3541 Gateway Blvd. Fremont, CA 94538-6585 USA TEL: 1-510-687-6100 USA: 1-800-824-8074 FAX: 1-510-687-6101 Company proprietary Data and specifi cations subject to change without notifi cation Not for distribution without prior permission from TCI. 550-11-05-12 2004-2012 TCIAll Rights Reserved 550 Summary Specifi cations Model 550 Specifi cations PolarizationVertical Radiation Patterns Elevation: See patterns at right Azimuth: Circular with 0.75 dB Input Impedance50 Ohms VSWR 2.0:1 or less in specifi ed frequency range Environmental Performance Designed in accordance with EIA Specifi cation RS-222C for loading of 190 km/h (116 mi/h) wind (higher environment models available) Power Capability See “Power and Impedance Data” below.
