1、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 55
2、0-6 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
3、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 ante
4、nna 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 rigidi
5、ty, 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
6、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 synthe
7、tic 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 INT
