Mere amplification of a weak signal also amplifies the noise in the same frequency range. What's called signal to noise ratio is not necessarily improved. This is actually more fatal in data communication than in speech or even music because of the required bandwidth being significently greather. The ideal aatena permits you to adjust the apparent antenna length and the dimensions of the tank filter that determines which frequency you get. Apparant antenna length determines the ideal receiving frequency for a particular antenna. bs On Wed, 12 Mar 2003, Paul wrote: > An antenna, maybe an omni, is a better option than an amplifier.
