以前习惯性的搜索“2x6 antenna switch”...通常找到的都是kk1l,
今天用“6x2 antenna switch”,又发现了新的。
我没有个能力diy和组织器材了,作者在最后的总结说的一番话,也很有意思: :d
it might seem like a lot of trouble to go through all of this work just for a remote coax switch but if you have a need for such a thing, options to purchase one are limited. now that i've done the project, i can see that the array solution's sixpak at $400 is not an excessive price. the lesson learned here is that the omron my4 relay doesn't work that great above 10mhz or so. if it weren't for the fact i had many of the components already in my junkbox, it wouldn't have been cost effective to build myself based just on parts cost alone. but it provided an interesting project that resulted in a useful station accessory.
大意是:看上去做这个玩意,遇到了不少麻烦事,其实可以去买一个成品,我看到array solutions的sixpak大概在400usd左右,也不算贵,但我现在自己做出来了。还有一个经验教训,所使用的欧姆龙my4继电器,在10兆以上的频率不是工作得很好。还有,在我的垃圾箱里面,多了很多零部件。好像付出的花费很多,不过,这就是乐趣所在了。
