db= lenght of antenna? Someone help.
My thought process on an antenna is very immature. If my db is between 3.7 and 26.5, Wouldn't my antenna need to spec out accordingly? I assume each individual piece of metal should match the tv stations db in inches? How do you find an antenna like that?

No, it doesn't work anything like that.

dB is an abbreviation for decibel. http://en.wikipedia.org/wiki/Decibel
It is a useful mathematical form, used to express ratios (one value divided by another). Pay attention to the presence or lack of a suffix... When you see just "dB", a simple ratio is being expressed, the two values should be identified in the context of the value. When you see "dBm" the value expressed is relative to a standard power level of 1 milliwatt (1/1000 Watts). There are many other suffix possible. A quick search will usually yield a definition. Here is a very basic 'how-to' that may help you translate the information in your TVFR into an educated estimate of how much gain you need an antenna to have in your application. http://forum.tvfool.com/showthread.php?t=109 |
