什么电视天线最好用？Rabbit Ear! wooddiy2010-03-18 20:01:59

Do you wast money on fancy HDTV antennas: they are not that useful anyway. My solution is very simple: a Rabbit ear one (which is free) plus a good antenna amplifier. You can get a Moto one for $60 or so. The benefit is, that kind of amp usually come with split inside. So you can distribute your TV signal through out house. You will need splitter anyway! Gain is ~20dB-3xSplits. For example a 1:4 split will reduce 12dB to 8dB or so. A single amp from China will cost $5 for 30dB gain. :) 20miles from stations, all my signals are at full strength and not directional.

看在哪里，有人在远郊用架到几十米高的大天线也没戏，在电视

haha, agree. So the amp gain is important.

如果信号太弱，放大器只能放大噪音，没有用的。

现在都是数字信号，去噪音是很容易的。

几十年前，电视超视距接受曾经是很时髦的活动。

RF 信号和数字信号是不同的，不满足一定的SNR, TV就没法工作。

八木天线好啊，

pls , name of the $5 amp and where to get it ?
