Offering plug-and-play functionality, it features an integrated Unun impedance matching unit at the base, delivering excellent VSWR levels of less than 1.5:1 across all bands when used with an external antenna tuner (ATU).<\/p>\n<p>With an overall length of 6 metres and a continuous reception frequency range spanning from 2.0 to 90 MHz, this high-performance fibreglass version combines lightweight construction, visual discretion, and outstanding mechanical resilience against wind and environmental corrosion. It eliminates the need for complex, tuned radial ground planes, making it an ideal choice for base stations with restricted space on rooftops, balconies, or gardens. It incorporates a standard SO-239 (UHF female) connector at the base and includes mounting hardware compatible with mast diameters ranging from 25 to 42 mm.<\/p>\n<hr \/>\n<h2>Key Advantages<\/h2>\n<ul>\n<li><strong>High Power Handling Capacity (1000W \/ 1kW):<\/strong> Reinforced version capable of supporting high-power transmissions with linear amplifiers without overheating the base transformer.<\/li>\n<li><strong>Continuous Multiband Coverage (80m to 6m):<\/strong> Allows operation across all amateur radio bands from 3.5 MHz up to 50 MHz using a single coaxial feed line.<\/li>\n<li><strong>Broadband Reception Range (2.0 to 90 MHz):<\/strong> Excellent performance as a general-coverage receiving antenna for shortwave listeners (SWL), utility signals, and low VHF.<\/li>\n<li><strong>Integrated Unun Matching:<\/strong> Base equipped with an impedance transformation unit that facilitates quick tuning (VSWR &lt; 1.5:1) via an external antenna tuner.<\/li>\n<li><strong>6-Metre GRP Fibreglass Construction:<\/strong> Tubular sections resistant to UV radiation, salinity, and harsh weather conditions with zero regular maintenance required.<\/li>\n<\/ul>\n<hr \/>\n<h2>Recommended Applications<\/h2>\n<h3>Urban Base Stations with Space Limitations<\/h3>\n<p>A discreet vertical footprint solution for apartment rooftops, spacious balconies, or courtyards where deploying long 40m or 80m dipoles is unfeasible.<\/p>\n<h3>High-Power and DX Operators<\/h3>\n<p>Designed for radio amateurs utilizing linear power amplifiers up to 1 kW who require quick band-switching agility supported by an automatic or manual antenna tuner.<\/p>\n<h3>Shortwave Listening (SWL) and Monitoring Stations<\/h3>\n<p>Uninterrupted coverage from 2 to 90 MHz ideal for communications receivers, SDRs, and spectrum analyzers.<\/p>\n<hr \/>\n<h2>Technical Specifications<\/h2>\n<table style=\"width: 100%;
