Sure.. two antennas would make it easy, but with the SteppIR, you can do it 
with just one.  Not necessarily the same performance as a dual antenna 
setup, but might be good enough.  After all, for the local paths, the path 
is shorter, so the fact that you've split your power into two "off 
horizontal" lobes (one high, one low)might not be much of an issue.  And, 
anyway, a lot of the advantage of beam antenna (particularly on receive) is 
not so much in the gain, but in the directivity:  You wouldn't have to 
listen to those DX thunderstorms (or broadcasters)
