Hi Roy:
Thanks for the freq info -- it looks like a possible range of about 3 to 24
KHz (I presume that is KHz). Can a single antenna be used for that wide of
a range? If I recall antenna theory, the antenna is sized for a specific
freq. If Q is high, it is more receptive to the tuned freq but rather
narrowband. If Q is low, the Q curve is pushed down making the antenna
more broadband, but lower reception strength overall.
What practical antennas are in use for this freq range?
thanks,
gil
