Circular wide band steel FM dipole 2500W

描述

Circular polarized antennas offer slightly less omnidirectional range/gain than vertically polarized dipoles, but they offer better penetration and are less sensitive to multipath problems. Circular polarization ensures better signal in urban environments, especially city centres with high buildings.

All of the antennas below are omnidirectional, circular polarization and wideband no-tune. Very resistant, entirely made of stainless steel with PTFE insulators, demountable into several parts for easier shipping. For best performance they must be mounted on a pole without any other antennas or metal structures neraby. If you plan to use sevaral of these in a multi-bay setup please email for instructions. Distance between antennas in multi-bay systems is important.

重要的： 由於這些包裹尺寸較大且形狀不規則，網站經常會錯誤地計算運費。有時我們還必須使用木箱，這會增加大約 100 歐元的天線成本。有關確切的運費，請聯繫我們的銷售部門，請務必向他們提供您的確切地址，他們將為您提供運費報價。 要求特別折扣也沒什麼壞處。

推薦配件： 我們推薦 AA-230 ZOOM 天線分析儀 用於檢查天線的 SWR。可以購買接地套件 這裡，它們確保防雷。它們應安裝在天線處（如果需要，大多數偶極子無論如何都會接地）、塔基和發射機大樓的入口處。還使用 自封膠帶 它會變成橡膠，防止濕氣進入您的天線系統。
