架设四套天线，守听2009年CQWW比赛，附加德国大台DR1A天线塔群图 [复制链接]

  这两天在家架设了四套大型天线，包括3.7mhz（50米高的dp单波段）、7mhz（40米高三单元对数周期单波段）、14-30mhz（六单元对数三波段）、14-30mhz gp，全程关注本次cqww比赛，在多个频率听到我们b7m的声音，在昼夜不停地qso，看来b7m收获应该不错。

  10月24（bjt，下同）晚3.7mhz传播不错，干扰少，信号质量好，美国都开通了；
  10月24晚7mhz过度热闹，邻频干扰厉害；
  10月24晚短暂时间14m开通了欧洲，10月25早晨开通美洲，听到b7m做w电台，看来天线不错，10月25白天14m也不错，
  10月25早上28m开通，主要是日本和东南亚、澳洲电台，
  10月25白天21m非常热闹，日本人偏爱21mhz，满地开花，欧洲电台也不少，国内电台不多；
  由于家里有小孩，只接收不发射回答，使用两台yaesu ft-950机器连接4套天线，减少切换时间，目前接收记录8页电台日记，估计有200多个收听记录。

  很关注b7p超级大鸟，80米波段2单元八木的通联效果，10月24晚在3.79 mhz附近听了b7p的声音，没白费工夫。

  这次cqww比赛期间，个人感觉传播算比较理想，各波段的电台非常频密，只能节选守听一些有兴趣的比赛台、稀有台。

1号塔：（抽空再翻译）

build-up: 03.04.2004 - beams: 15m-stack 5 over 5 element yagi since 24.04.2004

it is a 24m high wind wheel mast with ball race and where upon a 14m mountable steal tube tower is placed, from which an overall height of 38m results.
it is thereby our presently largest mast.
since the structure we developed the 15m stack with the two 5-element-yagis of on7lr but in the future we will install the 15m-stack at tower 5 in the same height, in order to be able to install here a 20m-stack.

2号塔

[url=]build-up: 31.07.1999; beam: hiygain 155 since 31.07.1999[/url]
the tower is a 18m high grid tower with 1m*1m set length.
this mast is a section of a 48m tower, which had been already diminished 1991.
since 1999 we installed there a 5 element yagi for 15m at a ham iv rotor.
soon we will develop a 10m stack here.
the turning unit will be on the ground and an approx. 30m long revolving tube will turn the two 10m beams.

3号塔

[url=]build-up: 29.07.2000; beams: 20m-stack 5 over 5 element yagi since 07.09.2002[/url]
the tower consists out of a conical 18m grid tower (a 12m rwe electric power mast), which we extended by 6m.
the turning unit is on the ground and turns a 32m long revolving tube with the 20m stack over 500 degrees.
the 20m stack consists of two 5 element yagi antennas of on7lr.the first antenna is 19m above ground, the second one 31m above ground.
the antenna boom has a length of 16m.

4号塔

[url=]build-up: 29.07.2000; beam: 40m 3-element-beam since 09.09.2006[/url]

the first part of this tower was build up in july 2000 and 19m high. the tower has a side length of 2m*2m on the ground. on the first 12m the mast approaches conical up to a side length of 1m*1m.
first we installed the 5 element yagi from hygain for 10m here at a ham iv rotator.
for cqww ssb in 2004 we developed a 5 element yagi for the 20m band here.
in september 2006 we installed another 15m long section on the top of the tower to it´s finally height of 34m over ground.
the 3-element-fullsize-beam for 40m is installed at the top of a 35m long revolving tube, turned by the turning unit on the ground.

[url=]build-up: 31.07.1999; beam: shorty-fourty since 20.10.2004[/url]
up to now we had a 30m grid mast from westerntower there.
so far we had used this mast for 40m, 20m and 2 * 10m yagis.
with the mast action 2004 we had to prepare the upper section of the mast with all antennas for its future task.
at present it measures a height of aprox. 26m, however in the future it will increase up to 37m.
here a revolving tube is to be built as with the tower no.3, in order to construct here a 15m stack in the future.
since the cqww ssb 2004 we developed a second antenna for the 40m band here.

6号塔

[url=]build-up: 03.04.2004; beam: 20m 5-element-cushcraft since 30.04.2006[/url]
we diminished the tower in february 2004 at a former german federal armed forces location.
the mast approaches from 3m*3m over a length of 30m conical to 1,3m*1,3m side length.
at a hight of 29m above ground is a 4m*4m large platform.
since the cq wpx cw 2004 we have the 3 element yagi for 40m installed there, but that the antenna crashed in a snowstorm in cqww-cw 2005. after that we installed a 5-element-yagi in april 2006.
in the future we will extend this mast with further 12m to mount a 3 element yagi for the 80m band

7号塔

[url=]build-up: in future, but still not planned[/url]
this tower was diminished at the same location as tower 6.
it consists of 3 elements, each 6m long and it will be extended up to 25-30m.
until this happens the mast will probably still spend some time lying in peace on the antenna meadow.

8号塔

[url=]build-up: 03.04.2004; beam: 2* 10m 5-el.-yagi on7lr & 1* 105 hygain since 20.10.2004[/url]
in former times this tower was a portable radio mast and was diminished from us in october 2003.
it has a total height of 30m and on approx. 16m height we have a 2kw power light, so that we do not have to grope on the antenna meadow any longer in the dark.
in the future the second 10m stack will be installed here: one fixed usa 5 element yagi for the 10m band and an upper antenna of the same type rotatable.
since the cqww ssb 2004 we installed here also the old 5 element yagi from hygain towards the south.

dr1a （df0cg） 的天线塔群太牛啦，没有千万元的投资，估计难于实现这个规模。

dr1a，太毒了

太棒了，开眼界@！

走召弓虽白勺！

不是一般牛~~

再配个台词:哥呼叫的不是cq,是寂莫!

20091025 16:33 yt7z 59 15 21.225mhz 南斯拉夫 （南斯拉夫人的英语真是难懂，非一般人能学得来）

yt7z我也听到了，不过是在7mhz，第一个y是猜了半天才猜出来的。确实很难懂。

比实力.........

  dr1a的天线阵容非常豪华，但我们看到他们的电台设备并不豪华，都是比较普通的电台设备，计算机也比较老久，他们有六间电台室和一些起居室，非常简朴。

  我们从中看到的问题是，短波通联，天线及控制系统第一（我看占90%投资），设备第二（我看占5%），其他投入5%，只有良好的天馈系统，才能实现高效率。

  而我们国内大部分火腿反之，往往舍得几万购买电台设备，却不舍得几百购买天线，更不用说铁塔啦，馈电系统没有信号到机器，再好的dsp也是白费！效果可想而知。

  我个人观点，一向着重天线及馈电系统投入，有了信号，才有发挥的空间。

太疯狂了。。。。。。。。。。
