分享：阁楼安装HDTV电视天线

benbenli(大岭)
HDTV电视天线买回来快一年了（打折的时候买的$50，现在又在打折FOCUS 8-Bay Long Distance Multi-Directional (80+ mi/130+ km) HDTV UHF/VHF Antenna），一直放在家庭厅的地板上。信号差，人走动的时候影响信号。比较安装在阁楼和室外墙壁或烟囱，觉得还是安装在阁楼简单点，至少不担心大风吹。但是一直没上过阁楼。这两天在加保温棉上阁楼了，就顺便把电视天线安装了。

以前没上阁楼的时候不知道如何从阁楼拉电视cable到地下室一分多到各个房间。上到阁楼了发现已经有一根线从地下室经阁楼到主卧。于是把这根线剪断，加个一分二，从天线到这个一分二，一头到主卧，一头到地下室一分多再到各个房间。

安装天线比想象的简单很多。在阁楼最高处钉了一根竖的2x2木条，天线直接拧在木条上就很牢固了。

然后调天线角度。在http://www.xtek.ca/hdtvpointer/网站输入房子地址，就画出了房子到多伦多CN Tower和Buffalo的连线，吧地图放到最大，看连线与房子墙壁的角度，调节天线的角度。天线有2片，一片面向CN Tower，一片面向Buffalo。

然后电视机搜索频道，与SaveAndReplay.com上的频道对比，大部分频道都收到了，有几个没收到，另外还多收到几个频道(下表中蓝色文字)。本来有点担心经过2个分接器和到家庭厅这么长的线信号会不好，结果高于预期。

    • 发现搞错天线型号了，是FOCUS 360-Degree Adjustable 8-Bay Multi-Directional (45-80+ mi/70-130+ km) HDTV UHF Antenna $60 -benbenli(大岭); 2015-10-24 (#9731134@0)

        • 我没接地 -benbenli(大岭); 2015-10-25 (#9731751@0)
    • 我比你多收了2-3个台，主要是17，67。区别是我架设在户外，更高，而且是2台电视，用分配器分开的。 -columbus(Edgar); 2015-10-25 (#9731707@0)
      • 我的天线只有UHF，没有VHF，所以收不到 67 系列 -benbenli(大岭); 2015-10-25 (#9731748@0)
        • 请问为啥不买带VHF的天线呢，台还能多几个 -bobbob1(bobbob); 2015-11-2 (#9747298@0)

            • 哈哈，不过VHF也没几个台，没啥大损失。 -bobbob1(bobbob); 2015-11-3 {122} (#9747463@0)
              另外带VHF的天线会不会收UHF的能力会相对差一些呢？我家里有个VOIP AMPLIFIER （4 SPLIT），不知道可不可以和OTA HD ANTENNA合用？
    • 你住哪块啊？ -akoei(停车**枫林晚); 2015-10-26 (#9733094@0)
    • 到底是大城市，能收那么多免费台。我们这只有3-4个，不过不用额外的天线，插根铁丝就可以了。 -thickroad(四环胡同); 2015-10-30 (#9742094@0)
