All,

I am interested in experimenting with ferrite core receive antennas. I
have about a dozen .4 by 10 inch rods. The primary band of interest is
75m. My question is:

1. For best reception is it better to make a fat or a long antenna? I
cannot find much written about these antennas and have not found any
equations.

The literature states the efficiency of these antennas can range from a
10**3 to 10**6 a dipole of the same size. Let's not argue the high end
but accept the low end for discussion. Does this ratio refer to length
or diameter?

Is there a good primer source? I have the ARRL Antenna handbook.

Thanks - Dan
