是1.5吋吗？谢谢。并且背面不用覆铝箔吗？U/V的差转如不用，所有的高清全部在U段吗？普通电视能接受吗？再谢。

根据PDF的图，沿木棍的轴线方向的间距是6" ，而youtube 视频中是5 3/4”，看各位的作品照片，垂向两V的间距大约在 1 1/2",而PDF 图注明大约1/2“，成功的GM有具体的数值吗？

谢谢

没人能回答吗？请看到的大侠解疑。谢谢

就像当初珠三角地区看香港电视用的鱼骨天线？但港穗的距离不到200km，而且是U段。

Here is my tips to get Digital channel:

1. Antenna set up: you can check US station at following link:

http://www.fcc.gov/mb/engineering/maps/

By inputing your address, you can get which station is available in your location. you can drag the red mark to exact where the antenna is(using satellite map), and click stationon on the list, it will give direction. you can check If trees block it or not. But you should have some kind of signal for a good antanna. channel 5-1, and 57-1 should be ok at west island.

You can add a signal amplifier(booster) if the cable is long and signal is weak.


2. Check input: antenna connect to DTV input, make sure TV input is Air, local, or antenna, not Cable.

3. Search Channel:
If every thing is ok, signal is strong enough, you can automatical program,scan, search, add, or setup DTV(different name for

different TV brand). Save it before exit.

If signal is not strong enough or it is a indoor antenna, you had better to manual program, setup, scan, search or add channels. Since by reading the signal strength or SNR(signal noise ratio) on signal meter, you know which direction, locaton is good for which channel. You can add channel one by one by adjust antenna.

Following is channel list in Montreal region:

13, (22-1, 22-2), WVNY (ABC)
14,(5-1,5-2) WPTZ (NBC)
19, (2-1) CBFT (SRC), french
20, (6-1) CBMT (CBC)
22, (3-1,3-2) WCAX (CBS)
27,(17-1) CIVM,(TQc) Tele-Quebec , french
32,(33-1,33-2,33-3,33-4) WETK (PBS)
38, (57-1,57-2,57-3) WCFE (PBS)
42, (35-1) CFJP (TQS) french
43,(44-1,44-2) WFFF (FOX)


The first # is physical channel, second # is virtual or mapped channel. After set up, TV only display mapped ch#.

In west island, it is difficult to get ch 13, 19, 20. The antenna is normal for UHF and 13 is VHF. 19, 20 are transmited at the top CBC building, it may be blocked by royal Mt. Any other Channels should be ok if you fine tune the antenna.

Post your result if possible.

Good luck,

天线完工了，多收一个模拟台。可能是由于电视是普通电视。但所以的台都很清楚。

垫片和transformer在GUY的那家中国人开的店有卖的。那个U/V t 不是我原先以为的差转，是阻抗转换，是用同轴电缆的，扁平馈线可不使用。另外引入线如接在1/2略偏上似乎好于正中间。

Anyone wants to take the 8 pieces? ONLY the 2x4 v-shape pieces on both side of Antenna.

. . . . . . We striped the paint about 1 cm on each tip(all 16), receiving of digital signal got worst, less stable. Regular channel improved. We have made a new set of 8 pieces, not stripping the paint this time :p . Anyone wants to play with the old pieces, please let me know. Pick up at Berri MTR.

Nice day!

已准备第二套的8pieces,就等您的图了。谢谢！！另外如果背面覆铝箔，消重影的情况如何juxijuxi@gmail.com

到Futureshop买了一台digtal DTV Converter box接上这套天线后，我的tube TV 也能看转换后的HD台了，老一代电视焕发了青春。

请问价格？谢谢
