Default Antenna for receiving WWV/10MHz: am I asking too much?

I'm in Richmond, Virginia and I'm trying to noticeably improve my
reception of WWV's 10MHz signal from Fort Collins, Colorado. It all
seemed so simple, two weeks ago: wind some wire, solder a
connector, and Hey...presto! a clean WWV signal. grin!

It wasn't so simple, and I'm afraid I've let it become an "ego
thing" (see also: resource sink). I've outlined the problem below
in the hope that someone can either suggest something I haven't
already tried, or even point out something really dumb that I've
been doing and shouldn't keep doing. grin!


Frank, can't you erect anything outside at all? A 10 metre dipole, is after
all, only about 5 metres long. And if you can't do that, what kind of attic
do you have? If your house is oriented correctly, you could even build a
three element wire yagi pointed west inside the attic. Dimensions shouldn't
be that critical for receive only, and space the elements at about 2.5
metres. Basically one element at about 47 feet, one at about 49.3 feet, and
one at about 45 feet. Split the 47 ft one into two, feed it directly with
50 ohm coax, one side to the shield, one to the centre conductor, and you
have a three element wire beam pointed, hopefully, west. (Put the longest
element on the east side, the shortest on the west.)
