Hi C2,

Can you possible explain what is ment by a 50 ohm match, does this mean that all components must add-upto to 50 ohms including the ariel?

Only just a brief calcultion it appears I am going to be using much larger value resistors for instance...

I've not calculated anything on this scale since I did my electronics servicing course in 1995 so could do with a hand...

Also what is meant by stacking gains...

I know an amplifier has a gain etc are you referring to adding these together...

Any help on the circuit and values would be much appreciated...

Attached is a pdf that does appear to contain a pre-amp and filter for a band pass filter, would this be useable...
