5单元3波段高增益天线

2017-04-14 15:16
5单元3波段定相双驱动多波段高增益天线

近几年来,HB35C天线是利用最先进的三波段天线技术进行研发设计的高增益天线。该款5单元3波段天线的相位调整既不是标准线圈的陷波器天线设计,也不是一个线性的陷波设计。因为所有陷波都有损失,需要缩短天线,因此降低了天线的效率。
HB35C在全尺寸频段下有效地采用革命性的HB9CV系统和“PHASE TUNED VK2AOU多波段系统的双重驱动系统。
这两个系统的结合与TET-Emtron独特的设计使HB35C天线性能表现更加优越。
与标准7 – 8单元的三波段横梁相比,这种天线具有优越的增益和带宽。此外,HB35C优秀的方向性也是它领先所有的竞争对手的地方。
HB35C所有波段的性能被认为是比一个全尺寸的三单元八木的性能更好。
该款天线是由高硬度铝管加工制作,所有硬件均采用不锈钢材质以满足在最恶劣的环境条件下使用。
BD8MI根据图片比例整理的参考尺寸:主梁4米(2+0.4+0.4+1.2),20米波段反射10.6米(匹配线1.5+1.5米)、振子5.2+5.2米(匹配线1.3+1.3米)、15米波段振子3.3+3.3米、10米波段感应振子5米,引向8.2米,天线转向半径5.67

5 element TRI-BANDER – HB35c – Tet Emtron

The HB35C utilises the most advancedthree-band antenna design developed in recent years.
This phase tuned 5 element TRI-BANDER isneither a trap antenna of standard coil design, nor is it of a linear trapdesign. All traps have losses and shorten the antenna, consequently reducingthe efficiency.
The HB35C is a full size tri-bander,efficiently utilising the DUAL DRIVE HB9CV system with the revolutionary PHASETUNED VK2AOU multi band system.
The combination of these two systems withTET-Emtrons unique design makes the HB35C a unique antenna withsuperior performance.
When compared with a standard Triband beamon a 78 metre boom, this antenna exhibits superior gain andbandwidth. In addition, the excellent directivity of the HB35C places it aheadof all competitors.
The performance of the HB35C on all bandsis considered better compared to that of a full sized wide spaced three elementYagi.
The antenna is manufactured from speciallyhardened aluminium tubing and supplied with all stainless steel hardware tomeet the most rugged environmental conditions.
