Anyone have any idea as to the probable performance characteristics of
two whip 40" whip antennas mounted approx. six inches apart, and used
for receiving shortwave, primarily between 6 MHz and 12 MHz? Would they
be more receptive to a signal approaching f/b, as opposed to s/s? Just
wondering... Hoping someone can offer some advice as to whether they
would be in any way directional.

They would be directional at the frequency where
6 inches is 1/8 wavelength. :-)

Hey Cecil, thanks for the reply.

Hmm. So, correct me if I'm wrong, but from what you're saying they would
actually have some directional characteristics at approx. 2.5 MHz.

I don't get that number at all. Splitting the difference between 6 and 12
Mhz, say
9 Mhz, an 1/8th wavelength distance would be about 4 meters.
Anybody have a url of a page that shows receive pattern of two antennas at
different
spacings, 1/8, 1/4, 3/8, 1/2 wavelengths?
Dave, I recommend you download the demo version of EZNEC, it won't take
to long to model a couple of verticals at different spacing.
