Certainly no security guru here, but simple RF engineering maybe. ;-)
I keep my AP in my basement. The RF goes upward vertically okay, but
the concrete foundation walls tend to absorb 2.4 GHz RF pretty
effectively. Depending on your setup, windows and other things may not
make that an effective option.
The other comments were good about the bank being SSL, etc. Everything
I've read about good security is that it's layered. More layers, more
hope for security. I say "hope for security" because nothing is 100%
secure.
Unless someone's specifically targeting you personally for some personal
reason, making yourself a harder target than the guy "next door" is
usually more than adequate. It's getting hard to NOT to find an open AP
when driving around these days. Grab a copy of Netstumbler and throw
one of the laptops in the passenger seat sometime, don't even bother
with an external antenna. You'll be surprised/amazed.
