sorry,i didn't see anything, and nothing new else,perhaps
不如直接贴上来,或者给个连接。

testing:

however -- test wise it isn't bad i got it tuned up on 40 meters at about 8 feet off the ground and it has an swr 1:2 to 1:5 from 7.30 to 7.175 mhz (without a transmatch). also does ok on 15 meter - tune up wise. bad news the performance is not great - signal pick up is several s units below my dipole, but it does work. from what i have read the antenna has problems in that most of the performance is based on feedline radiation (see the links below):

既然发在我们中国人的网站上,就是要国人都能看懂,达到交流学习的目的,既然没人翻译,只有我来做丑人啦。

--------------------------------------
天线测试:

  然尔,wise的测试并不坏,我把天线调整到40米波段,天线安装离地高度约8英尺,从7.30--7.175mhz的驻波比是1:2--1:5(没有连贯匹配),在15米波也可以工作,调整了wise,表现没变差太多,信号表显示,比我的dp少了几个s,但是可以工作,我查阅有关天线问题资料,是因为大部分的信号是基于馈线辐射(见下面的链接)


--------------------------------------

没看全文,觉得“wise”很怪,应该是个专用名词?不象是形容词(“合理、明智”),改天看完全文再修正翻译

关键是最后一句,性能不如dipole,接收少几个s,而且主要靠馈线辐射

这天线把balun省了是什么道理?

发觉这个所谓tak-tenna天线振子的水平部分实在是太短,效果怎么会好?况且还没有巴仑品匹配!40米段水平部分至少要保证12米以上,效率才不至于打很大折扣。1:1的巴仑还是应有的。

看到eham.net上的TAK-tenna,就搜索网络居然搜到坛子里来了。这天线看来不算很新的东西,效果有但是不算特别好。

顺便说一下,wise这里是个后缀词,表示“从......方面来看",“按照......的方式",比如,time-wise或timewise,意思是"从时间上来看"。所以句中test wise,就是从测试结果来看。还有一处是tune up wise,整句意思是“往上调谐,在15米也可以”。
