这种铝合金振子材料哪里有的卖？ [复制链接]

今天在buddipole网站看到这个振子，感觉很便携和轻盈，特发帖咨询：

military style shock-corded whip antenna

these shock-cord whips are custom made by us to be extremely rugged yet light-weight. these are the same whips that we sell to our military customers who are using these in harsh conditions and need a reliable and quickly deployable solution.
material selection is 7075 aluminum with all brass fittings. weight for each 3-section antenna is approximately 6 ozs.

(picture 1 shown with the standard 3-section version)

one unique feature of these whips is the ability to add or remove sections to change the overall length of the antenna. with 3 sections the overall length is roughly equivalent to our current telescopic whips (64"). by adding a 4th section (see the drop down menu below) the overall length is increased to 85".

the maximum recommended number of sections for a horizontal dipole is 5 (106") and for a vertical antenna 7 (148") sections.

(picture 2 shows both 3 and 4 section versions)

the shock-cord that we have custom-made for us is called "extreme shock-cord” and is designed to be used even in below freezing environments. it utilizes a double stitched cover over two extra stiff rubber cores.
this is the best shock-cord available for outdoor use in all conditions. the internal shock-cord is replaceable should the need ever arise. adjustments to the shock-cord length to accommodate additional whip sections are made at either end of the antenna via a small fitting.
these whips are meant for anyone who needs a more durable and/or quickly deployed antenna for use with the buddipole, or as a replacement whip for any vertical antenna.  


我仔细观察，这种振子和我们夏天用的一种面包蚊帐或者野外帐篷骨架材料很相似，全铝合金材质的！

你在淘宝里搜索连接杆就出来了！

吼吼，buddipole

我有一套军机121a的天线，就是这种的
内部有根橡筋，拿出来一抖就硬了

另外：淘宝：“连接杆”没收获
搜出来的都是角磨用的什么什么

直接找2根军机鞭天线就可以用，而且相同规格部份可以直接加长(133鞭天线)

铝合金帐杄

今天bg8gcg朋友告诉我，叫：天幕支撑杆/铝合金天幕杆/天幕支架。

用玻璃钢鱼竿，十几块钱就有一根了。

问题是玻璃钢鱼竿不是导体啊！必须加导线做振子哦！用这个就直接是振子哦......

一般来讲7075铝合金的刚性好,重量轻,就适合做这种东西!
