I would suggest that bending the outer portions of each
leg won't really hurt radiation too much, but I'd try to
keep those bends equal on each side and be kept as close
to straight as possible.  Just on general intuition, I
would also try to bend them in opposite directions for
balance.  See below.

Good luck!                      \

I figured I might be opening Pandora's box by mentioning
the actual antenna. It has worked well for me although I
have no way of comparing the actual performance.  One
thing I did find, with the help of tech support at B&W,
is that you CAN'T using small diameter coax.  I had a
run of good mini RG-8 and the antenna was next to useless.
I emailed B&W and was told to put in RG-8 or RG-213.  That
made a ramatic difference in the antenna - it went from
useless to performing very well.

I'm severely limited as to what I can put up.  For one
thing, the homes are close to each other here in the area
of Seattle that I live in.  On top of that, is the
structure of the father-in-law's apartment building.  It
has a flat roof and the outside vertical surfaces are
backed by chicken-wire.  Both of these restrict what I
can do.  My goal right now is to at least get something up.

We're sort of stuck here.  Father-in-law is legally blind
and very unstable when he tries to walk so we're taking
care of him.  When he passes away, we'll be getting our
own home & then I can put my tower and beam back up.  Only
good thing with this situation is that we don't have to pay
any rent for a very nice 3 bedroom apartment.
