什麽電視天線最好用？Rabbit Ear!

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.

• haha, agree. So the amp gain is important. -wooddiy- ♂ (0 bytes) () 03/18/2010 postreply 12:43:48

• 如果信號太弱，放大器隻能放大噪音，沒有用的。 -冬心- ♂ (0 bytes) () 03/18/2010 postreply 14:29:49

• 現在都是數字信號，去噪音是很容易的。 -千裏一盞燈- ♂ (0 bytes) () 03/18/2010 postreply 18:22:01

• RF 信號和數字信號是不同的，不滿足一定的SNR, TV就沒法工作。 -冬心- ♂ (0 bytes) () 03/18/2010 postreply 19:37:27
