"Get free HDTV
Since TV went digital, you no longer need cable to receive local broadcast
network HDTV channels. For static-free reception, all that's required is a
digital antenna (and a converter box if your TV is analog instead of digital
). To find out which antenna will work for your location and which channels
you'll receive, simply enter your address at antennaweb.org. Although you
won't get paid cable channels anymore, you may be amazed at how many HDTV
channels are free (the |

Stanford somehow does not allow service TV/cellular antenna on campus,
except exclusive deal with ATT.
It has been true. At least for now, it is difficult to receive NBC or Fox on
campus by antenna. |

Yes. The best smart phone with the most advanced antenna design loses signal

I am switching away from Comcast to Dish + anttena for local channel. Looks like when my parents go back, we can just stay with the antenna.. Enough for local news + a few excellent public television without advertisement.

同于1-2 watt的手机。
你举本书贴在脸上半小时估计也受不了了，别说一个两三瓦的热源了。
给你举个例子，n年前俺在学校实验室的小anechoic chamber测天线，5分钟就头晕了，
其实那时用了一个超小的发射功率，0.1w都不到。
现在整天跟10w的发射功率打交道，根本不晕。以前是因为那破房间太矮太压抑，黑咕

发帖数: 18 | 38 看来阁下是专门研究无线电的了。算是找对人了。
“tower antenna最大功率方向是平行于地面方向，你在tower下面，等效能量密度也就
等同于1-2 watt的手机。”
这一点我有异议。tower是两个，building一头一个。一个在我家正上方，另外一个在
另头，我家头上的算是轴线方向，辐射小，但另外一个发射的信号是否会影响到我呢？
我不知道你所指的“等效能量密度”是如何算的。但我估计可能比手机还弱。手机的
RFR，我用我那仪器可以测到的（10cm内），但tower发出的信号测不到。算是低辐射，
但时间长啊，每天起码>12h不断被辐射。
“你举本书贴在脸上半小时估计也受不了了，别说一个两三瓦的热源了。”
这个不合理，用座机时也是贴着脸的，比手机还大，不会有不适啊。
阁下还是认为是心理作用在坐怪了？我真心希望如此，但事实可能非也。我出现不适症
状是在我发现tower之前的。并非我发现了tower，才感觉不适。
谢谢你的安慰。
希望给点建议，如何才能把那tower弄走？ |

2. 微波（英语：Microwave）是指波长介于红外线和特高频（UHF）之间的射頻电磁波
。我们买的这个meter的最后一档就是Microwave，测的就是高频，测量结果绝大多数地
