New ! Chameleon Antenna 7.0-54.0 MHz CHA WINDOM 40

全新变色龙天线 —— 7.0-54.0 MHz CHA WINDOM 40横空出世


The CHA WINDOM 40 antenna is designed for 40m, 20m & 10m. A tuner may be needed to tune the other bands between 80M and 6M. Power handling is 250W SSB. Built with the portable user in mind. Very light weight. Does not require an antenna tuner under normal circumstances. SWR is < 2:0 (Typically a 1:3 to 1:6 ) at about 35′ to 45′. The antenna SWR is influenced by the balun elevation, wires angle, feed-line length and structures proximity.

CHA WINDOM 40天线专为40m,20m和10米段设计。配合天调可在80米到6米段间使用。天线可以承载250W 单边带发射。该产品注重便携,重量轻。正常情况下使用天线不需要天调。该天线在35-45英尺高度架设,驻波比小于2.0(通常在1.3-1.6之间)。天线巴伦的架设高度,振子角度、馈线长度和比邻建筑物都影响着天线驻波比。


The following SWR chart shows the SWR curves of the CHA WINDOM 40 elevated at about 10′ of elevation and installed in an inverted “V” configuration. A RigExpert AA-520 and a 50′ long RG-8X coax cable were used. The SWR will be influenced by the antenna elevation, the angle between the two legs and by the coax length and type.

下面的驻波比图表显示 CHA WINDOM 40 天线在10英尺高,倒V安装下的的驻波比曲线。使用RigExpert天分仪和50英尺长的RG-8X通州电缆。SWR会受到天线高度、两根振子的角度及同轴电缆的长度和类型的影响。



Antenna total length is 66′. Antenna wire elements are #16 proprietary stranded wire (short side is 22′ (6.7m) long and longer side is 44′ (13.4m) long). Built with a 5:1 250W SSB balun mounted on a polycarbonate plate. A 10’ of paracord 550 has been added at each ends of the antenna and another 20’ to secure the balun.

天线全长66英尺。组成天线的有#16专用绞线,短边22英尺长(6.7米),长边44英尺长。(13.4米)。该天线配有一个安装在聚碳酸酯板的5:1 250 w单边带巴伦。10英尺的的伞绳 550已经安装在每个天线末端,并多出20英尺来固定巴伦。
